The creation of industrial waste processing technologies is of great ecological and
economic importance. The achievement of high technological indicators in the enrichment of
metallurgical waste slag by flotation depends on the composition, size, mineral and phase
composition of copper and other valuable components, the method of preparing slag for flotation
and the adopted enrichment technology.

oven. The constant growth of the population in a developed time and the increased demand of
mankind for resources also leads to the need to switch to their rational use. As a result of the rapid
development of the mining and processing industry in recent decades, the demand for division into
precious metals has also increased[1].
In the modern metallurgical industry, technologies for the enrichment of non-ferrous metal ores
require significant improvement, which is due to a decrease in valuable components and a
complication of mineralogical composition. It assumes the development and application of
scientifically based methods of improving the efficiency of processing minerals, reducing material
costs for processing, increasing the environmental safety of mining and processing, and
regulating[2]. Today, as a result of the decrease in mining, the demand for waste in non-ferrous
metallurgical plants, slag and slurry of the metallurgical industry, residues is increasing. The
problem of processing metallurgical slag and choosing the most effective technology for separating
precious metals from them and their widespread use is the most important task for mining
enterprises in today's conditions[3]. Also, unprocessed metal slags are stored in the landfills of the
enterprise and at the same time occupy a very large area, polluting the environment. Slag processing
not only reduces metallurgical waste, but also achieves an economic effect, which means not only to
receive additional benefits, but also to reduce the negative impact on the environment.
Copper slag is being considered more recently as a resource for copper production. The total copper
slag in the world is 30 million tons. Accordingly, many waste slags are almost unused by
accumulating near smelters. With this, very large areas of land are occupied and lead to the loss of
precious metals. So, from the point of view of the environment and resources, it is necessary to
develop a suitable technology when extracting precious metals from copper slag. Today, in
pyrometallurgical production of copper in the Olmalyk Mining Metallurgical Combine, the amount
of precious metals contained in waste slag from smelting furnaces is growing. For example, oxygen-
torch furnace slag contains around 1% copper, while converter furnace slag contains around 2.5-3%
copper. This is a much higher indicator than the allowable amount for the exhaust. Waste slags with
such a pointer need to be recycled, and waste slags cannot be used as building materials because
they contain large amounts of precious metals[4]. The technology that allows you to get the most
complete and cheaper when extracting copper and precious metals from slag is flotation. Flotation

funds will not be spent.
