About company
Largest Kaolin Deposit — Zhuravliniy Log
The enterprise is engaged in enriching production and has a line for metakaolin production (heat treatment of enriched kaolin) and a production laboratory that carries out product quality control and prosecution of research in new spheres.
Large variety of kaolins
The Zhuravliniy Log deposit contains more than 60 mln tons of primary kaolin developed reserves. The deposit has five large fields of
Kaolins are subdivided into natural types depending on their source rocks:
- normal kaolins from granite,
- alkaline kaolins from granite,
- normal kaolins from gneiss.
The deposit is unique because it contains kaolins of different chemical and mineralogical composition as well as quartz sands with minimum content of coloring oxides. All this allows the enterprise to produce not only qualitative kaolin and quartz concentrates, but also kaolin and sand mixtures.
Selective mining, sorting and composition control
Primary storage of raw kaolin is carried out by chemical composition.
Formation of graded stockpiles — accumulators, averaging inside grades — is the guarantee of high quality and consistency of the composition of output products.
Enrichment
Modern technology of dry enrichment method allows maintaining or adjusting of natural rheological properties of kaolin concentrate, production of quartz sand and related products — aluminosilicate composite (premix).
Sparing drying schedule of raw kaolin, disintegration of the dried raw materials with further classification by size and specific gravity of the particles to obtain materials containing kaolin and quartz of specified chemical granulometric composition.
Kaolin calcining
Selection of raw materials for calcining (of enriched kaolin) according to the mineralogical, chemical and granulometric composition is the key to obtaining products of the calcining of a given composition. In the production of metakaolin manufacturer uses innovative technology of calcining — contactless calcining. This guarantees homogeneous heating of each kaolin particle. Modes of heat treatment have a significant effect on the activity of metakaolin.
Low calcining temperature leads to incomplete dehydration of the raw product; high calcining temperature leads to sintering and formation of mullite. The selected temperature mode and duration of calcination allows producing of high quality metakaolin based on kaolin concentrate of Zhuravliniy Log deposit.
Quality control
The production laboratory is equipped with the equipment necessary for express analysis of the quality of products of enrichment at all process stages of technological process. At the same time in the company’s laboratory the methods for testing the products quality for compliance with regulatory documents were developed and implemented.
