The deployment of renewables and electric vehicles is expected to skyrocket as the world strives to reduce greenhouse gas emissions.. These lowcarbon technologies currently rely on a handful of key metals, some of which have been littleused to date.
Copper production About 80 % of primary copper production comes from lowgrade or poor sulfide ores. After enrichment steps, the copper concentrates are usually treated by pyrometallurgical methods. Generally, copper extraction follows the sequence (see Figure below): 1. Beneficiation by froth flotation of ore to give copper concentrate
Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Silver processing, preparation of the ore for use in various products. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen. The lustre of the pure metal is due to its electron configuration,
