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.

Due to the similar surface chemical properties and similar flotation behavior between barite ore and associated salt minerals, the flotation process and the flotation reagents used in the different barite ores are different.

If the content of phosphorus and sulfur is over a certain amount, the mechanical behavior of pig product would be influenced. Therefore, phosphorus and sulfur need to be removed in iron ore processing stage.

According to the different oxidation rate of ore, the copper ore can be divided into copper sulfide, copper oxide and mixed copper ore. The copper flotation process used in the various copper ores are also different.

Hematite (weakly magnetic mineral) is a common iron ore, which is often extracted by magnetizing roasting magnetic separation, gravity separation, flotation, high-intensity magnetic separation and combined iron extraction processes.

The common iron re-processing technologies are single magnetic separation technology, gravity-magnetic separation combined technology, flotation-magnetic separation combined technology, and flotation-magnetic-gravity separation combined technology.

There are many kinds of alluvial gold deposits. The gold is in a free state in the alluvial gold deposit and has the obvious specific gravity difference with sand, so the gravity separation process is an ideal and efficient method to extract gold from placer.

According to the property and composition of the ore, the processing flow of potash feldspar includes the following steps: crushing, washing and desliming, separation, and dewatering process.
