Bioleaching is the extraction of a metal from sulfide ores or concentrates using materials found native to the environment; namely, water, air and microorganisms. In other words, bioleaching is the commercialization of the ability of certain bacteria and archaea, found in nature, to catalyze the oxidation of sulfide minerals.

Copper is a chemical element.It is the 29th element in the periodic table and has 29 protons.Its mass number is 63.55. It is a transition metal in the middle of the periodic table. The symbol for copper is "Cu", which comes from the Latin word cuprum, which, in turn, came from the Latin word for the island of Cyprus, where copper was found.

The rock particles sink and the lead and zinc ores are skimmed off. Then the lead ore is separated from the zinc ore. A chemical called a depressant is added which is soluble in water (for example, zinc sulfate) and the zinc ore sinks and the lead ore is skimmed off.
Overview. The first step in a conventional production flow sheet for converting manganese oxide ore to alkaline grade electrolytic manganese dioxide (EMD), which is a high purity product that possesses the 'recipe specific' electrical characteristics desired by batterymakers, is a high temperature pyrometallurgical roast process, wherein the manganese ore is heated to between 800°C and ...

Copper + Nitric Acid . Copper is a reddish-brown metal, widely used in plumbing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny. (Although since 1983, pennies are actually made of zinc surrounded by a paper-thin copper foil to give them the traditional appearance of pennies.)
A mini ore pad 15 m × 15 m × 0.5 m deep was constructed on top of a waste-rock dump at the Fazenda Brasileiro mine site. The base of the pad was lined with a geo-textile and then filled with about 150 t of low-grade oxide ore. The plot was designed to contain two ore preparations.
