Process research in the sphere of mineral processing is one of the basic activity areas of Scientific and Production Association "RIVS".
SPA "RIVS" develops and implements new benefication technologies for the following types of minerals:
• Nonferrous metal ores.
• Auriferous ores.
• Iron-bearing magnetite and hematite ores.
• Nonmetallic minerals.
• Mining chemical feedstock.
• Industrial raw materials.
The Association conducts an overall battery of studies, including:• geological and mineralogical evaluation of deposits which includes process chart preparation, core sampling, and testing;
• material composition analysis;
• mineralogical studies;
• physical and chemical analysis techniques for minerals;
• large-scale process research, selection of the expedient mineral processing flowsheet and modes of mineral processing;
• elaboration of process procedures for minerals benefication; |
Studied processes

Complex approach of SPA "RIVS" to the development and implementation of modern minerals benefication technologies allows to:
· Increase market product output by:
- increasing of metal recovery into concentrates;
- improving concentrate quality;
- reducing metal losses in thickening and filtration operations;
- increasing processing plants capacity.
· Decrease processing costs for 1 ton of ore;
· Decrease specific power consumption;
· Use waste tailings for backfilling;
· Use total water circulation in production cycle;
· Decrease the emission of contaminants into the environment.
