Gold CIL (Carbon in Leach) Process is an efficient design of extracting and recovering gold from its ore. By cyaniding and carbon leaching crushed gold ore slurry simultaneously, CIL process lower the gold mining operation cost and increase gold recovery rate to a degree of 99%. View details
According to the complex and changeable market situation in home, Xinhai Mining ...
There are a variety of iron ores in nature, mainly including magnetite, haematite, limonite, siderite, so the beneficiation of iron ore needs the suitable process to improve the economic benefit. The beneficiation of iron ore needs a series of process, including crushing, grinding, magnetic separation, flotation, gravity separation.
Cyanidation has a history of more than 200 years since it was applied to gold and silver ore extraction in 1887. At present, cyanidation is still one of the main gold extraction processes due to its high recovery rate, high adaptability to ore and local production.
There are many kinds of silver ores in nature, among which the silver-bearing ores with production value include natural silver, gold and silver ore, argentite, pyrargyrite, horn silver, dyscrasite. The silver ore is often associated with lead-zinc, copper, gold, and limonite, and can be recovered with other minerals. In this paper, we will start with the mineral properties of silver ore, take you to understand the method used for the extraction of silver ore.
In the nickel processing method, the processing of nickel mineral is divided into copper sulfide mineral processing method and nickel oxide mineral processing method.
In this passage, we will discuss the difficulties in carlin type gold recovery and methods of carlin type gold recovery.
In the production, the methods used for theextraction of iron from haematite are not single, mainly include the froth flotation method, magnetic separation method, gravity separation method and roasting magnetic separation method.
Cyanide leaching is one of the main technologies of gold extraction. For this technology, the cyanide leaching recovery rate is determined by the efficiency of the leaching operation.
The gold heap leaching process is that, the gold-bearing ore broken to a certain size is piled up on a leak-proof base of asphalt, concrete or plastic. The ore is sprayed with cyanide solution from above to dissolve the gold, and then the gold is extracted in this way.
In flotation systems, there are many types, such as preferential flotation, bulk flotation, partial bulk priority flotation, branch stream flotation, speed flotation, etc. In the flotation systems, there are also flow paths such as one stage flotation, multiple stage flotation, etc.
