SnapshotThe Iron Ore Department (Orken LLP) is a complex of four enterprises in Kazakhstan. Main activity – mining, processing and concentration of iron ore and subsequent delivery of finished products, iron ore concentrate, to the main customer – Qarmet JSC.

The Lisakovsk Iron Mine is a part of Orken's LLP Iron Ore Department. The mine mined and treats oolite iron ore to produce concentrate.

The Lisakovsk branch carries out the full cycle of operations – from overburden removal and ore extraction to its crushing, gravity-magnetic beneficiation, drying, and shipment of the finished product to customers.

As of August 2024, the modernization of the beneficiation facility in Lisakovsk is planned.

Deposit type

  • Oolitic ironstone

Summary:

The Lisakovsk deposit is located within the western side of the Turgai trough, in the Eltaisko-Kurzhunkul ore region. It was formed by sedimentation processes and the filling of the Lisakovskaya river valley. It is a shallow sheet-like deposit, elongated along strike for 100 kilometers with a width that varies from several hundred meters to 6 kilometers. The iron mineralization at Lisakovsk occurs as an oolite deposit containing mainly hydro-goethite and goethite. The deposit has relatively high phosphorous content which can limit its utilization in the steel-making process.

A characteristic feature of the deposit is that the ore was located almost on the surface. Such an arrangement of the ore body makes it possible to efficiently and economically develop the deposit using modern high-performance mining and transport equipment with insignificant capital and operating costs. The total geological reserves of oolitic ores are 6 billion tons, under the subsoil use contract - 1 billion tons. The field is a plateau-like deposit, stretched along the strike for 100 km and a width of several hundred meters to 6 km.

The iron ore deposit at Lisakovsk, North Kazakhstan, is a limonitic one of oolitic type and the major iron minerals are goethite and about 0.5 % magnetite. The gangue minerals are predominantly quartz and clay like minerals such as carbonates, chlorite and other aluminosilicates as reported in a comparative study by Kosava et all. The phosphorus content in the iron concentrate is about 0.6 – 0.8 % and the studies has shown that it is not represented as separable from iron minerals species.

The iron mineralization at Lisakovsk occurs as oolite containing mainly hygogoethite and goethite. The phosphorous content in the mineralization limits its utilization in the steel-making process.

The main ore mineral is hydrogelite, nonmetallic is quartz. According to texture-structural genetic
characteristics and physical properties, oolithic ores are divided into two types: loose oolithic
and massive. Three structural species are distinguished in the ores: thick-oolithic ore composed mainly of ore oolithes (50-80%) with a subordinate amount of cement and quartz; rareoolithic ores, consisting of ore oolithes (less than 50%) with predominance of cement and free quartz and fine-oolithic cemented ores. A component of the oolithes is the hydrogenerite of two generations with a finely dispersed admixture of ferrochlorite clay substance. The sizes of oolithes range from 0.05 to 0.60 mm, 0.2-0.6 mm predominate.

Layered natured ores are often of the oolithic structure, often deformed, consists mainly of hydrogite, chlorite and calcium phosphate. Oolithes are fissured, so they resist weakly to grinding. Magnetite is represented by thin crystalline particles smaller than 0.005 mm. The ore can be slightly oxidized (martitized). Chlorite belongs to the chamoisite type, it contains magnesium and ferrous iron. Calcium phosphate belongs to the apatite group, its molecule can contain one or more OH groups and, possibly, a little SiO2 instead of PO4 (Muhammed M., Zhang Yu. 2011). Its morphology can be different - amorphous and pseudohexagonal. A theory is known that phosphate anions absorb and grow on the surface of the gel ferrohydrate and phosphorus is excluded from the iron ore lattice inside the crystals of liquid cement dehydrate and recrystallized.
