LEAD CONCENTRATE

Sormak Mining Company, with an annual production capacity of 4,000 tons of lead concentrate, is one of the most important suppliers of lead concentrate to the National Iranian Lead and Zinc Company. It is worth mentioning that in the near future, with the use of new technology in the field of flotation cells, the results presented below will increase significantly. Sormak Company offers two types of lead concentrate, sulfide and carbonate, separately.

GILSONITE
(Natural Bitumen)

Gilsonite is a solid, brittle, shiny material with high luster. It is physically and chemically similar to coal (fossil fuels) and bitumen (petroleum products). Its main difference from coal is its softness and melting before burning. Also, its main difference from bitumen is its hardness and the properties of its polar molecules, which give it dispersing properties. The fundamental difference between gilsonite and natural and synthetic hydrocarbon minerals has made it used in most industrial applications as a unique mineral in terms of physical and chemical properties. Gilsonite is divided into three grades: ordinary, sorted, and sieved, which are classified based on their melting ...

IRON ORE

The iron ore produced by Sarmak Company is in the form of hematite and is extracted from the Ahangaran mine in Malayer and is very suitable for use in the cement industry. For this purpose, the produced iron ore is offered in two ranges (0-40) mm and (0-300) mm. Over the past 30 years, more than 25 major cement producing companies in Iran have been buyers of Sarmak Mining Company's iron ore, including Sepahan Cement, Behbahan, Karun, Ramhormoz, Nahavand, Saman Gharb, Hegmatan, Gharb, Ekbatan, Fars, Saveh, Dorud, Zanjan, Kurdistan, etc. It should be noted that the iron ore of Sarmak Mining Company is of the low-grade hematite type and is only used in the cement industry of the country.

COAL

Coals are sedimentary and fuel materials that are formed by the accumulation of plant remains in land swamps or on seashores through diagenetic processes after chemical, physical, and biological changes. This substance is formed through changes called the coalification process. During the coalification stages, organic matter is first converted to peat, and in the following stages, brown coal (lignite), bituminous coal, and in the final stages, anthracite and graphite are produced. With the increase in the degree of coalification from peat to anthracite, the carbon content of coal increases, and ash and volatile matter decrease. Therefore, the quality of coal increases.

Chromite

Chromite | Exploration, Mining, and Processing at Sormak Mines Chromite (FeCr₂O₄) is a strategic mineral in the ferrochrome and stainless-steel value chain. Sormak Mines, with a focus on targeted exploration, disciplined mining, and the design/implementation of chromite processing circuits, works to convert mineral resources into marketable products (chromite concentrates in various grades).

Copper Cathode

Copper Cathode from Oxide Ore | Hydrometallurgical Production (SX–EW) at Sormak Mines Copper ores are generally classified into two groups: sulfide and oxide. Oxide ores typically form near the surface through weathering and oxidation of primary minerals and, due to their higher solubility in acidic media, they are a highly suitable feed for hydrometallurgical copper production. With an end-to-end view from mine to product, Sormak Mines operates in the design and implementation of copper cathode production routes from oxide feeds.
