Copper mining in the United States
Copper mining in the United States has been a major industry since the rise of the northern Michigan copper district in the 1840s. In 2017 the United States produced million metric tonnes of copper, worth 8 billion, making it the world's fourth largest copper producer, after Chile, China, and Peru.

Atmospheric acid leaching of nickel laterites review: .
This review first considers the mineralogy and reactivity of nickel laterites including selective leaching of various ore types (viz. limonite, smectite, saprolite).It then examines developing technologies that focus upon the following:
Cyanide Leaching Of Gold
It is not used much anymore, because most leaching is heap leaching, carried out in the outdoors, where drip emitters or sprays distribute the cyanide solution to a large structure of gold ore, called a "heap". And while the pile of ore is called a heap, it is not a haphazard pile of rocks. Much thought and design goes into the making of a heap .
Gold extraction
Gold extraction refers to the processes required to extract gold from its may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
