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.
Gold flotation process is one of the most widely used methods for treating pulse-gold ore in the gold concentrator. In most cases, the gold flotation process is used in the treatment of gold-bearing ores with high reproducibility of sulfide minerals with good separation effect.
The types of gold ore are different according to different classification methods. According to the degree of ore oxidation, the type of gold ore can be divided into primary (sulfide ore) ore, partially oxidized (mixed) ore and oxidized ore. Here are the gold mining processes used for five types of gold ore.
As to the extraction of silver, the flotation process is generally used for the extraction of independent Ag deposit, while the combined process of single flotation method and floatation-gravity separation method and floatation-cyanidation method are used for the extraction of the common and associated silver. But the flotation process is still the most important silver extraction process.
How can we improve the flotation mineral process effect by improving the bubble mineralization process? The more important factors include bubble size, mineral surface properties, mineral particle density and particle size, etc.
In the flotation technology, it is necessary to consider not only the selection of flotation agent, dosage, dosing time, but also the charging capacity, pulp concentration, PH value and other issues. In order to determine the appropriate flotation process flow, equipment and reagent before the formal production, improve the field production indicators, improve the mineral recovery rate, and reduce the processing cost, the flotation experiment needs to be carried out. Flotation test mainly includes three steps:
The common froth flotation process of sulfide ore mainly includes priority froth flotation process, mixed froth flotation process, iso-flotation process, differential branching flotation process and potential-controlled flotation process.
Gravity separation method is one of the oldest and most common gold mining processes. In the sand gold deposits, the gold usually exists in the form of monomer natural gold, and its particle size is generally more than 16t/m3, which has a big difference with gangue density, so gravity separation method is the most effective and economic gold mining process.
