التعدين في السعودية – ويكيبيديا
Mining in Saudi Arabia The kingdom’s vast mineral resources include bauxite, silver phosphite, zinc, copper and gold, with resources estimated at 20 million tons of gold and precious metals and 60 million tons of copper; The kingdom’s vast and undiscovered lands provide enormous possibilities for exploration, as these lands contain resources.
The history of mining and mines in the Kingdom of Arabia The history of mining and mineral exploration in the Arabian Peninsula dates back to more than 900 years BC, through the presence of gold mines that were exploited, and the mining activity continued during the period of the eighth and ninth centuries AD during the era of the Umayyad and Abbasid Caliphates to exploit gold and silver mines.
Mining and mines began during the reign of King Abdul-Aziz, when the Mahd al-Dhahab and Zolm mines were exploited between the years 1939-1954 and 1952-1954, respectively.
In 1933 AD, a liaison office was established for the oil and mineral sector, under the umbrella of the Saudi Ministry of Finance, to supervise the search for minerals in the Kingdom.
In 1934 AD, the Saudi government signed a mining agreement with the Saudi Arabian Mining Syndicate (SAMS), a Saudi-British-American company, to search for minerals and operate some old mines, such as Mahd al-Dahab, Dhalam and As-Suq. In February of 1935 AD, Prince Faisal bin Abdulaziz Al Saud, who was then the viceroy of the Hijaz, ratified the agreement with the “Saudi Arabian Mining Syndicate”, and the syndicate began its work in operating the old mine in Mahd al-Dahab on the first of March 1935 AD. .
In 1939 AD, the “Saudi Arabian Mining Syndicate” extracted and concentrated gold and silver minerals from the Mahd al-Dahab mine, where work continued there for 15 years, during which more than 900 thousand ounces of gold were produced, and more than one million ounces of silver, which contributed to supporting The national economy and the settlement and employment of Bedouins in that region.
Saudi Arabian Mining Company “Ma’aden”[عدل]
In order to develop the mining and mining sector, the Kingdom established the Saudi Arabian Mining Company “Ma’aden” by Royal Decree No. 17/M dated 11/14/1417 AH (3/23/1997 AD) as a Saudi joint stock company with a legal personality and an independent financial liability with a capital of four thousand million riyals. Saudi.
Ma’aden is focused on operating five gold mines, including: Mahd Ad Dahab, Al Amar, Sukhaybarat, Bulghah, and Al Hajar. The company is expanding its activities to include the development of phosphates, the aluminum project, and other projects that include base metals and precious metals, and the company cooperates with the government and local legislators to develop a regulatory framework for managing and regulating the mining and mining industry in the Kingdom of Saudi Arabia.
Division of mineral ores[عدل]
Mineral ores or deposits can be divided into metallic and non-metallic.
- metallic mineral deposits, including the following
- Precious metals: such as gold, silver and platinum group.
- Non-ferrous metals: These include copper, zinc, lead, tin, and aluminum.
- Iron and ferrous metals: These include iron, manganese, nickel, chromium, tungsten, molybdenum, vanadium, and cobalt.
- Trace metals and associated nonmetals: These include tantalum, niobium, titanium, rare earth elements, uranium, zirconium, beryllium, magnesium, antimony, bismuth, cadmium, and mercury.
- Non-metallic mineral deposits, including the following
- Ceramic materials: such as clay and feldspar.
- Decorative stones: granite, gabbro, marble and limestone.
- Metallurgical and refractory materials: such as fluorite, graphite, lime and limestone, magnesite.
- Chemical industry minerals: such as phosphates, rock salt, sulfur, and potassium salts.
- Industrial materials: mica, talc, asbestos, barite, sulfur.
- Building materials: gypsum and aggregates.
- Ornamental minerals: such as diamonds, sapphires, and turquoise.
The geology of the Kingdom is distinguished by the existence of two geological regions:
- Arabian Shield area
It is parallel to the Red Sea, covers a third of the Kingdom’s area, and is the main region in which gold and silver minerals are found, and base metals such as copper and zinc, in addition to some industrial minerals.
- The second region east of the Arabian Shield
Where sedimentary rocks of different geological ages appear, and contain some industrial minerals, especially bauxite and phosphate minerals.
Mineral deposits are spread in the Kingdom in many locations of the Arabian Shield, and the majority of metallic minerals ores are found in the Precambrian rocks that make up the Arabian Shield in the western part of the Kingdom. On the mineral side, we find that there are mineral deposits that are characterized by a certain company of rocks. Gold and silver deposits are found in many igneous, metamorphic, and sedimentary rocks. The most important deposits are fissure-filling deposits, which are found along with quartz in the veins and in the welding of the breccia and other voids. Gold is also found in the form of placer deposits in river or modern coastal beds.
When we trace the sites of gold-bearing quartz veins in the Kingdom, we find that the concentration of most of them is around a line running from south to north in the middle of the Arabian Shield, between Najran and Dhalam, then Hail, to some extent layered – with the seam of Nabith suture.
The gold and silver-bearing quartz veins cut through the different types of stratified and overlapping rocks in the Arabian Shield. The mines of Mahd al-Dhahab, Al-Amar, Sukhaybarat, Bulghah and Al-Hajjar are among the most important gold-bearing sites in the Kingdom.
There are deposits of nickel and a group of platinum elements in peridotite or serpentinite rocks, and deposits of tin and molybdenum in granite rocks. As for deposits of base metals such as copper and zinc, they are associated with volcanic or clastic rocks of volcanic origin.
The metallic and non-metallic mineral sites or presences discovered in the Kingdom amounted to about 5076 sites, as the number of metallic mineral sites reached about 2424 sites, constituting 47% of the total mineralized sites. Mining activity in the Kingdom can be divided into two main parts:
- The activity related to the extraction of metallic minerals necessary for the manufacturing industries “mines”.
- The activity related to the quarries containing the raw materials needed for building and construction, to meet the needs of the building and construction industry and some other industries.
Explorations continued for mines containing gold, base metals (copper and zinc), industrial minerals and rocks, with the aim of discovering new resources, and providing good targets and information for investors in the field of mining and mines in the Arabian Shield, in addition to searching for promising economic deposits, whether in the Arabian Shield. , or in the sedimentary cover of the Kingdom.
The survey and exploration work for metallic mineral ores in the rocks of the Arabian Shield resulted in the identification of a large number of sites, including about 980 sites for gold, 610 sites for silver, 856 sites for copper, 477 sites for zinc, 282 sites for lead, 76 sites for nickel, and 117 sites for chromium. , and 176 sites for rare elements.
The most important mines[عدل]
The following are some of the most important mines in the Kingdom:
- Mahd al-Dahab mine: It is located in the western region of the Kingdom within the Medina region. Mining operations are carried out by “subsurface or tunnel mining”, and the total length of roads in the mine exceeds 60 km. The site contains a processing plant to separate metallic minerals. The mine extracts and processes about 185,000 tons of ore annually, with a concentration of about 10 grams, a ton of gold. Production in 2007 was about 85,257 ounces of gold, more than 116,170 ounces of silver, 737 tons of copper and 800 tons of zinc.
- Sukhaybarat mine: It is located in the Qassim region, approximately 250 km north of Mahd al-Dhahab. Free or loose gold is found in diorite rocks, as well as around the edges of the crystals of arsinopyrite and its internal cracks, and in the quartz veins and the edges of the veins. The open mine includes a carbon washing plant, in which the ore transported from the Bulghah mine, 65 km from Sukhaybarat, is processed. The production capacity of the Sukhaybarat mine is 600 thousand tons per year. Gold production was about 25,000 ounces of gold and 3,259 ounces of silver in 2007.
- Bulghah Mine: It is located within the Madinah region, 65 km south of the Sukhaybarat processing plant, and includes an open-pit mining mine. The low-concentration crude is processed at the mine’s washing and filtration plant, while the high-concentration crude is sent to Sukhaybat for processing. Gold production in 2007 was about 43,299 ounces and 4,972 ounces of silver.
- Al-Amar Mine: It is located in the Riyadh region to the southwest of the city of Riyadh. It is a subsurface mine. Gold ore is processed at a rate of 200 thousand tons per year to produce gold in the form of a mixture of copper and zinc concentrates. Production started at the beginning of 2008.
- Al-Hajjar Mine: It is located in the south of the Kingdom near Al-Aqiq Governorate, and it contains a washing and filtration plant. There is gold in the form of loose, fine-grained, and the reserves are estimated at about five million tons, containing 6 gm tons of gold.
- Zinc in Al-Hunaiqiyah: This site is located 170 km west of the city of Riyadh, and contains about 5.1 million tons of ore, with a ratio of 11% zinc and 0.88% copper. About 145 thousand tons can be mined annually by the subsurface mine method, to produce two types of ore concentrates as follows: 34,400 tons with a concentration of 56% zinc, and 2400 tons with a concentration of 25-30% copper. Or extracting 290 thousand tons annually by the surface mine method to produce 54,800 tons of zinc concentrates, in addition to 4800 tons of copper concentrates.
- Jabal Sayed: It is located 40 km north of Mahd al-Dahab, and 400 km north-east of Jeddah. The site contains the largest deposits of base metals associated with volcanism in the Kingdom. The site contains about 20 million tons of ore, with a percentage of 2.68% copper. The ore can be extracted using the underground mine method at a rate of one million tons per year, in order to produce “76” thousand tons per year of copper concentrates, with a concentration of approximately 30% of copper.
The most important mineral deposits[عدل]
Phosphate rock deposits are located in Hazm Al-Jalamid in the north-east of the Kingdom. Studies have shown the existence of reserves of phosphate estimated at about 313 million tons, in addition to the presence of bauxite deposits in the Zubaira region, with estimated reserves of about 250 million tons. Bauxite is currently being developed and mined to produce alumina with a production capacity of 2.4 million tons per year, and aluminum with a production capacity of 650 thousand tons per year.
There are a large number of sites that contain industrial minerals that can be extracted using the surface mining method, including:
- Phosphates in Saudi Arabia, in the Al-Jalamid area, 120 km southeast of the city of Tarif.
- Bauxite in the Zubairah region, 200 km southwest of Hail.
- Magnesite in Al-Ghazala Governorate, 160 km southwest of Hail.
- Silica sand in Jabal Burm and Jabal Al-Daghm, 40 km north-east of Riyadh.
