Technological scheme of ore processing

At the beneficiation plant for processing polymetallic ore, it is planned to use modern, high-tech equipment with a high degree of automation to ensure stable operation of the technological process, achievement of the required production indicators and minimal impact on the environment.

The enrichment process includes four main stages:

• coarse, medium, fine crushing in jaw and cone crushers and fine crushing in high-pressure grinding rollers (HPVD);
• grinding;
• selective flotation;
• fine grinding of the main zinc flotation concentrate
• dehydration.

Crushing and grinding processes are used to achieve the required particle size before releasing useful minerals, a factor that is critical to the subsequent flotation process.

Flotation process based on the difference in the physical and chemical properties of the surface of minerals. To separate valuable minerals from gangue minerals, flotation concentration uses chemicals called flotation reagents, with the help of which the physical and chemical reactions of the process are regulated. The range of flotation reagents used is traditional for direct selective flotation of lead-zinc ores.

The design scheme for ore processing makes it possible to obtain three enrichment products:

• lead concentrate;
• zinc concentrate;
• flotation tails.

All enrichment products undergo a dehydration stage. Lead and zinc concentrates, after thickening and filtering to optimal humidity, are packaged in big bags or in bulk in wagons for subsequent transportation to the consumer. After dewatering, flotation tailings are sent to a tailings storage facility for further storage.
