Disposal Methods on Solid Wastes from Mines in Transition from Open-Pit to Underground Mining

TLDR

Disposal of solid waste from metal mines requires selecting appropriate varieties for comprehensive utilization and controlling contamination from waste rocks and tailings, with environmentally friendly disposal being key. This paper aims to summarize and enumerate comprehensive utilization methods and propose new ideas for disposal and utilization of mine solid waste, such as reducing waste discharge by recovering sand for construction and mine backfilling approaches. The authors outline methods including recovering sand from ore dressing flow for construction and mine backfilling approaches to reduce solid waste discharge. The authors propose a process flow for tailings separation tailored to iron mines and provide guidance on disposing and utilizing mine solid waste.

Abstract

The important issues on disposal of solid wastes from metal mines are to choose the right varieties for the comprehensive utilization of mining waste and to control contamination from waste rocks and tailings. Environment- friendly disposal of solid wastes from mines is the key pathway. This paper summarizes and enumerates some comprehensive utilization methods and proposes new ideas on the disposal and comprehensive utilization of solid waste from mines, including reducing the discharge of solid waste by recovering sand from ore dressing flow for construction industry and a mine back filling approaches. The process flow of tailings separated for different purposes that could be carried out in iron mines is putting forward. The authors put forward certain guidance on disposing and utilizing of solid waste from mines.
