In the Almalyk mining region, in addition to the reserves identified for industrial development and exploited deposits, there are also unconventional resources – waste of enrichment and metallurgical redistribution of copper-molybdenum, lead-zinc, and gold ore deposits. Man-made waste from mining, mineral processing, and metallurgical production is represented by waste maternal primary off-balance sulfide ores and their oxidation products (balance and off-balance mixed and oxidized ores), tailings of the enrichment of copper-molybdenum and lead ores: slags; metallurgical production, etc., which are stored at AGMK. The principal disadvantage of the current technologies is the extraction of one useful component with a high content of associated useful components that go to waste. In the conditions of formation of market relations, the issues of industrial ecology by enterprises is given insufficient attention. The involvement of complex polymetallic raw materials in the processing by enterprises led to an increase in the resulting middling products, recyclable materials, and slag waste. Technologies created 30-40 years ago, were not adapted to the processing of this type of raw materials. Formed industrial products and other wastes due to the lack of rational technology began to accumulate in the territory of enterprises. As a result, even with a significant decrease in the volume of output, the damage caused by environmental enterprises due to the accumulation of large volumes of these products increases significantly every year. In the future, the main task of mining and metallurgical production should be to minimize the receipt of metal-containing waste into dumps by reducing the loss of metals in all production cycles: from mining and enrichment to metallurgical processing.
