Flotation process is one of the commonly used methods in the ore separation process. It mainly uses the floatability of mineral surfaces for separation. In the flotation process, the addition of chemicals is crucial. The type and dosage of chemicals added have an important impact on the flotation effect. Understanding the flotation process and types of flotation reagents is one of the main ways to optimize and improve the existing flotation process. The following will introduce you to the flotation process and types of flotation reagents.

Gold-copper ore beneficiation methods commonly used in actual production include flotation, gravity separation, electrolytic precipitation, volumetric extraction, magnetic separation, etc. The types of ores applicable to each method are also different. The gold-copper ore beneficiation methods will be introduced below by heap leaching and magnetic separation.

Common gold and copper minerals include chalcopyrite, bornite, cuprous sulfide, stibnite, tellurium gold ore (AuTe2), etc. These minerals are important sources of gold and copper. The presence of gold in copper ore deposits can significantly increase their value, and it is often economically advantageous to recover both metals simultaneously. In these deposits, the specific mineral composition and distribution of gold and copper can vary greatly depending on the geological body, so it is necessary to select appropriate ore beneficiation technology to improve the recovery rate of copper and gold.

There are many types of gold ore found in nature, and different types of gold ore may require specific beneficiation techniques. Common gold ore beneficiation technologies in actual production mainly include: flotation, gravity separation, cyanide, heap leaching, bioleaching, etc. The specific mineral processing technology should be selected according to the characteristics and production requirements of the gold mine. Below you will find some common gold ore beneficiation techniques and the types of gold ore they are suitable for.

As an important precious metal, the development and utilization of gold ore has great value. In the process of mineral processing, the recovery rate of gold ore is one of the very important indicators. The factors affecting the recovery rate of gold ore include the characteristics of gold mine, gold ore processing process and the management and operation of gold mine concentrator. In this paper, we will explore how they affect the gold mine recovery from these three aspects.

As a key equipment often used in metal ore beneficiation plants, ball mills can be used in the first, second, third or regrinding processes. The purpose of grinding is to dissociate and separate useful minerals and gangue minerals from each other, and secondly to provide separation process with suitable particle size for subsequent sorting operations. In actual production, the grinding operation often forms a closed circuit process with the classifying operation, so the too coarse ore particles in the grinding products may enter the regrinding process in the process for reprocessing, and the over-crushed minerals have no chance of recycling.

As a waste material produced in the extraction and processing process of tungsten ore, tungsten tailings recovery is also an important way to improve the utilization rate. Choosing the appropriate tailings treatment method can not recover valuable minerals, but also can reduce its impact on the environment. The specific techniques and methods of treating tungsten tailings can vary according to the ore composition, tailings characteristics and production requirements. The following will introduce four treatment methods of tungsten tailings, namely gravity separation, flotation separation, magnetic separation and hydrometallurgy.

Sedimentary rock-type apatite ore is usually rich in phosphorus elements, exists in the form of calcium phosphate, and is an important phosphate fertilizer raw material, widely used in agriculture. Therefore, the exploitation and utilization of apatite is crucial for global agriculture and food production. However, the issue of limitation and sustainability of phosphorus resources has also received increasing attention, and overexploitation of apatite may lead to resource depletion and environmental problems. The selection of appropriate sedimentary rock type phosphate mineral processing technology and equipment can improve the utilization rate of phosphate mineral resources and reduce the waste of resources.

Fluorite ore is an important industrial raw material, and the quality requirement of concentrate is strict, so it also puts forward higher requirements for fluorite concentrator. To improve the effect of fluorite beneficiation, you can consider optimizing the crushing and grinding process of fluorite ore, optimizing the fluorite beneficiation process, optimizing the use of fluorite beneficiation agents, etc.

The ore beneficiation recovery rate refers to the percentage of useful components extracted from the raw ore, and is an important indicator to measure the mineral processing effect. There are many factors that affect the recovery rate of ore beneficiation, mainly including the properties of raw ore, beneficiation process, and beneficiation management. The following will analyze their impact on the recovery rate of ore beneficiation in detail from these aspects.

As the residue of ore dressing, there are still some unfinished gold ore particles in the gold tailings. In order to make full use of resources and reduce environmental impact, reselection technology can be used. Generally, the density difference between mineral particles can realize the effective recovery of gold particles. The following will introduce four kinds of gold tailings gravity separation technologies, namely: shaker gravity separation, spiral chute separation, heavy medium separation and centrifugal separation.

Fluorite mineral is an important non-metallic mineral resource, and it is the main source of fluorine element in the industry. Fluorite ore has been widely used in metallurgy, aluminum smelting, ceramics, cement and other fields. But fluorite is often associated with quartz, calcite, barite and other minerals, affecting its taste. To recover the fluorite, the flotation method is often used. The use of collector and inhibitor is the key to fluorite mineral flotation, and the optimization of the process flow and the application of efficient flotation equipment also have an important influence on the flotation effect.
