Description

Technical Field

[0001] The utility model relates to the technical field of gold mine equipment, in particular to an ore spraying, washing and screening device for gold mines. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted or which has certain properties that can be utilized. It can be divided into metallic minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in an ore is called ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. Ore grade is often used to measure the value of an ore, but the composition of the vein stone (useless minerals in the ore or minerals with very little useful components and cannot be utilized) and the amount of harmful impurities in the effective component ore also affect the value of the ore. Ore dressing can enrich the useful components in the mineral, reduce the consumption of fuel and transportation in smelting or other processing processes, and make low-grade ores economically utilized.

[0003] Gold mine refers to gold ore or gold deposit (mountain). Gold ore is a mineral aggregate with sufficient gold content and can be used industrially. Gold mine is a place where gold is obtained through mining operations. It is a certain scale of gold ore accumulation that can be used industrially formed through mineralization.
