TENORM: Copper Mining and Production Wastes | US EPA

Copper mining waste storage piles may be as large as 1,000 acres and typically include three types of waste; tailings, dump and heap leach wastes, and waste rock and overburden. The amount of marketable copper produced is small compared toCopper Mining Waste | Wastes | US EPA,The document describes copper ore extraction and beneficiation operations with specific reference to the waste and materials associated with these operations and the potential environmental effects that may result from lead-zinc mining.Mining Waste Products - University of Exeter,Mining Waste Products. The types of waste materials generated are dependant upon the type of mining activity. Around the Fal Estuary there have been effectively three main types of mining activity: (1) the recovery of cassiterite from the river sediments (so called tin streaming or placer mining); (2) the underground and opencast mining for metal (hard rock mining); and (3) opencast mining

Mining for metals in society's waste - The Conversation

Mining waste rock from historic mines or even treated sewage to find useful metals and minerals could be a sustainable way to meet demand for these finite resources.USGS Minerals Information: Copper,Copper is usually found in nature in association with sulfur. Pure copper metal is generally produced from a multistage process, beginning with the mining and concentrating of low-grade ores containing copper sulfide minerals, and followed by smelting and electrolytic refining to produce a pure copper cathode.Mine wastes management - Mining and Blasting,Mining operations generate two types of waste rock - overburden10 and mine development rock. Overburden results from the development of surface mines, while mine development rock is a by- product of mineral extraction in underground mines.
