Coal is a mineral composed entirely of carbon, originally trapped by living organisms through the process of photosynthesis. The carbon in coal is therefore of organic origin which leads some authorities to object to the definition of a mineral as an inorganic substance. Limestone is a rock composed of a single mineral calcium carbonate.

Lime in Mineral Leaching. Leaching is an alternative process to flotation for the extraction of ores from mined rock. It utilizes the natural propensity of minerals to dissolve in percolating water and produces a mineral-rich solution. Mineral leaching operations optimize this process through the use of chemical leaching solutions (lixiviants).
