Mining Terminology C

• Captive stope: A stope that can be gotten to only through a man way.

• Carbon-in-pulp: A method of recovering gold and silver from cyanide solutions by adsorbing the precious metals to granules of activated carbon, which are characteristically ground.

• Cash flow: The net of the inflow and outflow of currency during a book-keeping stage. This however does not account for depreciation or bookkeeping write-offs that don’t have to do with the outlay of cash.

• Cathode: A rectangular shaped sheet of metal that is made by electrolytic refining, which is melted into commercial shapes such as, billets, ingots, wire bars and so forth.

• Cesium magnetometer: A geophysical instrument that takes care of measuring magnetic field strength as far as vertical gradient and total field is concerned.

• Chalcocite: A sulphide mineral of copper frequent in the sector of secondary enrichment.

• Chalcopyrite: Sulphide mineral  consisting of copper and iron

• Change house – The building in the mine where the workers change into work clothes and is also commonly known as the dry.

• Channel sample: A sample that is made up of pieces of vein or mineral deposit that have been cut out of a little trench or channel, typically about ten centimetres in width and around two centimetres in depth. 

• Charter: A paper issued by a leading authority when a company or other corporation is being created.

• Cinnabar: This is a bright red colored ore mineral of mercury.

• Circulating load: outsized hunks of ore that are brought back to the head of a closed grinding circuit before they pass on to the following stage of treatment.

• Clay: A well grained material that is made up of hydrous aluminum silicates.

• Cut-and-fill: A technique of stopping where the ore is taken out in slices or lifts. The excavation produced is then filled with waste material such as back fill or rock before the subsequent slice is extracted.

• Cut value: Applies to assays that have been reduced to some arbitrary at most to put off erratic high values from inflating the average.

• Cyanidation: This is a method of extracting exposed gold or silver grains from crushed or ground ore by dissolving it in a cyanide solution

• Cyanide: This consists of a chemical species that has nitrogen and carbon that is used to dissolve gold and silver from ore.
