The extraction of gold by cyanidation mainly includes CIP and CIL processes, which are similar but different. Let’s see the differences between the CIP process and the CIL process.

Refractory gold ore refers to the part of gold ore that cannot be extracted effectively by the conventional cyanide leaching process after the fine grinding. Therefore, how can we improve the gold leaching effect of the refractory gold leaching process?

According to the different associated minerals, the chrome mining processes include the single gravity separation, the single magnetic separation, gravity separation-magnetic separation process.

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.

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 mineral processes mainly include the physical quartz mineral process and chemical quartz mineral process. Among them, the physical quartz mineral process includes washing, classifying and desliming process, scrubbing process, magnetic separation process, and flotation process. The chemical quartz mineral 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.
