Carbon leaching method for gold extraction (CIL) means the activated carbon is added into the pulp, and leaching and adsorption of gold are carried out simultaneously.

At present, the common recycling and utilization of gold tailings mainly include the recycling of gold, the recycling of other associated non-ferrous or ferrous metals, and the recycling of non-metallic minerals.

Quartz sand extraction is a difficult extraction technology to remove a small amount of or microscale impurities in quartz sand and gain refined quartz sand or high purity quartz sand. In this passage, we will introduce several quartz sand extraction methods.

Due to the different ore properties of all kinds of vein gold ore, the extraction processes of vein gold are also different. The five extraction processes of vein gold mainly include single flotation process, all-slime cyanidation process and the combined gold extraction processes composed of gravity separation, flotation and cyanidation process.

Due to the different types and contents of valuable components in lead-zinc mine tailings, and their respective occurrence states, it is necessary to adopt a suitable lead-zinc tailings re-selection process according to their specific properties.

The flotation recovery of skarn-type tungsten ore often has problems such as difficulty in recovery and separation and poor recovery effect. This article will discuss the four major factors affecting the recovery of skarn-type tungsten ore and teach you how to solve the problem of skarn-type tungsten ore flotation.

In the practice, the wolframite processing flow or wolframite-based ores processing flow mainly include five stages: roughing, grinding, gravity separation, concentration and fine sludge treatment.

At present, there are about 300 kinds of iron-bearing minerals found in nature. According to the classification of chemical composition, the common iron ore mainly includes magnetite, hematite, limonite, and siderite. Below, we will introduce to you two different types of iron ore extraction processes.

​Different properties of iron ore, its processing technology is naturally different. Below, we will explain to you two different types of the iron extraction processes.

In this passage, we will introduce how slurry concentration, flotation particle size, and the rotating speed of flotation cells influence pyrite flotation.

The flotation process of single copper sulfide ore is relatively simple. The main principle is to carry out flotation and throw tailings under rough grinding conditions as much as possible, thus reducing costs, increasing economic benefits, and achieving good beneficiation indicators.

At present, the recovery and utilization of lead and zinc tailings are about the following aspects: reprocessing of valuable minerals, goaf backfill, and building materials, etc.
