Abstract. The current state of the mining and metallurgical industry requires a tendency to process man-made waste that has accumulated for many years. Depletion of rich ore deposits and increased requirements for environmental protection indicate the need for special attention to increasing the complexity of the use of raw materials and the use of innovative energy-saving technologies using man-made production waste. Waste after enrichment by flotation of copper production slags is a storage of iron-containing technogenic waste, which will serve as a raw material for the production of pigmented iron oxide compounds. The article states that oxide compounds are associated with silica, and the main task is to free from silicon dioxide and obtain pigmented iron oxide.
