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.
In general, the main mineral of natural silica sand and quartz sandstone is quartz, and some other impurity minerals are often associated with it, such as mica minerals, feldspar minerals and iron and aluminum oxide minerals. However, the mixing of these impurities greatly reduces the value of quartz sand and affects the quality of products. Therefore, it is necessary to carry out the impurity removal for the silica sand. Here are the silica sand purifying process and equipment for the silica sand processing plant.
Due to the different types of gold ores, the gold extraction methods from ore are different, mainly including gravity separation method, flotation method, amalgamation method and cyanide leaching method, resin in the pulp method, carbon paste adsorption method and heap leaching method. For some types of gold ores, the combined gold extraction methods from ore are often used in the gold processing plant.
Quartz sand is a common and wildly-used non-metal raw material. It is wildly used in glass, casting, ceramics, metallurgy, and chemical industries. The requirement of purification is strict in quartz mining. In this passage, we will introduce the quartz sand separations with common gangue minerals in quartz extraction. The common gangue minerals of quartz sand […]
The gravity separation method is an ideal and efficient alluvial gold mining process to extract gold from the sand. And the reasonable alluvial gold equipment is mostly the joint operation of several kinds of gravity separators.
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.
