Environmental impact of mining and beneficiation of copper …

In this study, the mining process of one tonne of copper-sulfur raw ore was selected as the functional unit. One tonne raw ore would be approximately transformed into 0.03 tonne of copper concentrate, 0.14 tonne of high-sulfur concentrate, and 0.02 tonne of low-sulfur concentrate through the mining and beneficiation process.

Processing of Nickel Laterite Ores on the Rise

The SX-EW Method. SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step.
