Visualized: The Silver Mining Journey From Ore to More
In 2020, 784.4 million ounces of silver were mined across the world according to Metals Focus. While production is forecasted to increase by ~8% to reach 848.5 million ounces in 2021, it’s still greatly outpaced by growing demand for silver. Silver demand is forecasted to see a 15% YoY increase from 2020’s 896.1 million ounces to Mining. Copper can be found in above-ground and underground deposits. The first step in copper production is mining. This can be done via open-pit or underground mining methods. Milling. Once the copper ore has been mined, it must be milled to separate the copper from the rest of the rock. This is done via crushing and grinding.

Potential environmental pollution from copper metallurgy
Copper production is complex and multi-stage: it involves mining, crushing, milling, ore concentration, smelting, refining and waste management. The metal ore mining industry, including copper, generates over 10 billion tonnes of slags, dusts and aerosols as by-products, which are contaminated with metals and metalloids, including toxic onesIn 2000, an in situ crushing leaching system was built at the Tongkuangyu copper mine in the Zhong-Tiao Mountains in China, and it achieved excellent technical and economic indicators, where the copper leaching rate was 77.87%, extraction recovery rate 99.5%, electrodeposition recovery rate 99.5%, and production cost RMB 8754.31 per ton In Situ Crushing Leaching Mining Method SpringerLink

Comminution Circuits for Gold Ore Processing ScienceDirect
Abstract. This chapter considers comminution for gold ores, starting with breakage induced in the blasting process, continuing through primary crushing, primary milling, and secondary milling. Both technical and operational considerations are reviewed; while gold ore comminution is broadly similar to like-sized circuits for other mineralChina is a major producer of copper concentrate as its smelting capacity continues to expand dramatically. The present study analyzes the life cycle environmental impact of copper concentrate production, along with selection of a typical copper sulphate mine in China. Life cycle assessment (LCA) was conducted using SimaPro with ReCiPe Environmental impact of mining and beneficiation of copper
