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.
At present, the common quartz mining processes mainly include the physical quartz mining process and chemical quartz mining process. Among them, the physical quartz mining process includes washing, classifying and desliming process, scrubbing process, magnetic separation process, and flotation process. The chemical quartz mining process is the acid leaching process.
In general, the single magnetite separation process usually adopts the weak magnetic separation process, while the polymetallic magnetite iron ore and mixed magnetite iron ore are usually separated by the combined process consisting of a variety of separation methods, including magnetic separation process, flotation process, gravity separation process, magnetization roasting magnetic separation process, reduction roasting magnetic separation process.
The common process used in the extraction of iron from limonite mainly include a single separation process and joint separation process.
According to ore types, raw ore properties, mine scale and application, the common barite mining processes mainly include handpicking, gravity separation, flotation, magnetic separation, and combined barite mining process.
At present, with the depletion of high-grade gold reserves, the research on middle and low grade, refractory gold ores and the enhancement of traditional techniques used for the extraction of gold have become the mainstream trend of gold extraction in the world. The common processes used for the extraction of gold mainly include cyanide gold extraction, flotation and gravity separation. Next, we will explain to you one by one the gold extraction processes.
According to the movement mode of the material during the leaching process, the chemical leaching process can be divided into the percolation leaching process and agitation leaching process. The percolation leaching process is a common mineral processing method used in the treatment of abandoned pillar, surrounding rock, tailings and low-grade minerals.
Tailings are the material in the concentrator that has a low content of useful components and cannot be used at present. And the tailings disposal is one of the important links in mineral processing. At present, the tailings disposal methods are generally divided into tailing reprocessing, tailing dehydration and tailing filling goaf. We will explain these three tailings disposal methods separately.
