Project Summary

Globally, issues of the rational use of natural resources by involving technogenic waste in the production cycle are relevant. This allows for a reduction in energy consumption for raw material processing and mitigates environmental risks. In the Republic of Kazakhstan, a large amount of technogenic waste has accumulated, including significant deposits of technogenic gold ores—enrichment tailings, etc., creating a significant environmental burden. These wastes were formed during a period when technologies for extracting gold from mineral raw materials were not yet perfected. Processing technogenic deposits can significantly expand the raw material base for gold production and reduce the harmful effects of technogenic waste on the environment. The development of such deposits has several advantages, as the raw materials have already been extracted to the surface and crushed. Typically, gold in tailings is found in the form of fine inclusions in sulfides that are difficult to process by cyanidation.

Project Goal: The development of new methods for processing refractory technogenic raw materials using the example of the enrichment tailings of the Maykain Gold Extraction Factory No.1.

Project Objectives:

1. Study the influence of microwave radiation power and frequency on reducing energy consumption, shortening the hydrometallurgical processing time, and increasing the extraction of precious metals and other valuable components from technogenic raw materials of the Maykain Gold Extraction Factory No.1 and flotation concentrate obtained from the technogenic raw materials of the Maykain Gold Extraction Factory No.1.
2. Study the influence of microwave radiation power and frequency on reducing the consumption of leaching reagents.
3. Study the influence of microwave radiation power and frequency on the kinetics and thermodynamics of the pre-treatment process of technogenic raw materials of the Maykain Gold Extraction Factory No.1 and flotation concentrate obtained from technogenic raw materials of the Maykain Gold Extraction Factory No.1.
4. Plan experiments using the probabilistic-deterministic method of Malyshev V.P. The application of this planning method will allow saving time and resources by reducing the number of experiments.
5. Conduct a scaled-up laboratory test with 200 kg of technogenic raw materials from the Maykain Gold Extraction Factory No.1.
