How do we extract minerals? USGS

The primary methods used to extract minerals from the ground are: Underground miningSurface (open pit) miningPlacer mining The location and shape of the deposit, strength of the rock, ore grade, mining costs, and current market price of the commodity are some of the determining factors for selecting which mining method to use.

Mineral Extraction an overview ScienceDirect Topics

Mineral extraction is associated with a diverse range of potentially adverse impacts on environmental and human health. A broad framework to assess potential direct and indirect risks is required, and must incorporate exposure information from geology, geomechanics, toxicology, and epidemiology. To optimize community safety, a major goal is to ensure that all stages of mineral extraction

Processes extraction, mining, smelting, refining

An ore is a rock containing enough valuable mineral to make it worth extracting. In the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (0.2%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and
