Technologies and equipment for mining and metallurgy waste management

Waste in the mining and metallurgy industries (barren rocks, low-grade ore and heap leaching tailings, which contain natural impurities) are stored as a rule in piles on ground surface. Mining and pretreatment of ore extracted from structurally complex bodies results in 1.4–1.6 t of waste per 1 t of marketable ore, which generates the environmentally unfriendly situation in the mining areas. The mining and metallurgy waste recycling (backfilling, construction of dames and special storages, etc.) allows disposal up to 50–60% of total waste volume, and the rest waste is subjected to repository, decontamination and disturbed land reclamation. It is shown that vibratory, mechanical and electrical activation of cemented paste backfill mixture components improves activity of binders (blast-furnace grain slag) and low-grade materials (low-quality sand, crushed rock, processing rejects and leaching tailings) by 10–40% per each machine. In particular, inert ore pretreatment on jigger screen GV–1,2/3,2 (Ukraine) increases strength (activity) of cemented paste backfill by 15–20%.

Keywords: mining and metallurgy industry waste, recycling, decontamination, land reclamation, eco-friendly and resource-saving technology, equipment, people life.
