The 3 most common commercial biomining processes are: 1. Slope Leaching. Fine ore is kept in a large, slope-shaped dump. During slope leaching, a water solution made of inoculum is continuously sprayed over the ore. After that, the leach liquor (or remaining liquid) is gathered at the bottom and processed for supplemental metal recovery. 2.

Bioleaching and phytomining are increasingly used to extract copper from low grade ores (see below). The traditional method of extraction is to heat the copper sulfide. Copper(II) sulfide gives copper and sulfur dioxide during thermal decomposition. Thermal decomposition means that the compound breaks down into other substances when it is heated.
