Lime use and functionality in sulphide mineral flotation

Nov 01, 2019· 2. Lime formulation, synthesis, and production 2.1. Calcination. Quicklime (CaO) is produced from the calcination of limestone (CaCO 3), a sedimentary rock of mainly marine sediments containing calcium carbonates in a range of crystal forms.The chemistry and the physical properties of the originating limestone significantly affect the calcination process and hence the final lime product

Lime in Flotation and Recovery Processes Graymont

Lime is used extensively in the recovery of gold and silver. Ores, either run-of-mine, milled, autoclaved or roasted, are combined with lime and a cyanide solution. The cyanide dissolves the gold and silver. Lime maintains proper pH in the cyanide solution, keeping it in the liquid phase and preventing the formation of hydrogen cyanide gas and its loss into the atmosphere.

Lime (material) Wikipedia

Lime is a calcium-containing inorganic mineral composed primarily of oxides, and hydroxide, usually calcium oxide and/ or calcium hydroxide.It is also the name for calcium oxide which occurs as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. The word lime originates with its earliest use as building mortar and has the sense of sticking or adhering.

Modeling and Control of Lime Addition in a Flotation Process

Flotation is an important and versatile mineral processing technique that is used to separate hydrophobic materials from hydrophilic. This technique makes it pos-sible to mine complex ores that otherwise would have been regarded as uneco-nomic and non-beneficial. In this case flotation is used to separate copper from the unwanted gangue.
