As a very precious resource, the beneficiation process of gold mineral is very difficult. There are many kinds of gold ore beneficiation methods used by the concentrator. Generally, the gold ore is sent to the crusher for crushing, and then sent to the ball mill for further processing. After grinding, gravity separation, cyanidation, flotation, etc. are carried out to further obtain gold ore concentrate.

With the sustained and rapid economic development, the iron and steel industry is also developing rapidly. It has also become a trend to develop poor and miscellaneous iron ore to meet the needs of the industry. Technicians have done a lot of beneficiation research on these ores. The following will introduce two iron ore reverse flotation separation technologies and the reagents used in the process of flotation iron ore.

There are different types of iron ore in nature, mainly divided into magnetite, hematite, limonite, siderite, ilmenite and chromite. The beneficiation methods adopted by different types of ores are of course quite different. The following will introduce you to the different beneficiation technologies of the above three iron ores.

Beneficiation is the process of physically and chemically separating valuable minerals from the gangue in ore. The goal of beneficiation is to increase the concentration of valuable minerals, thereby increasing the economic value of the ore. In actual production, there are a variety of iron ore beneficiation process technologies, but there are different types of iron ore in nature, and the applicable beneficiation technologies are also different.

Lepidolite is generally produced from granite pegmatites, and its color is purple, pink or light to colorless. It is one of the main lithium minerals in the industry at present. In order to effectively utilize lepidolite, scientists from all over the world have done a lot of research work and achieved many technical achievements in extracting lithium from lepidolite. The following will introduce to you the industrial applications or the researched lepidolite lithium ore extraction technology.

At present, the beneficiation method of lepidolite is mainly flotation technology. During the beneficiation process, lepidolite will go through crushing, grinding and other processes. After these treatment, some ores will have problems of over-crushing and over-grinding, which in turn will produce slime. There are also some slimes in the lepidolite raw ore, which will adhere to the mineral surface and affect the recovery of the concentrate, which has a greater impact on the flotation index.

Limonite ore is an important iron ore that exists widely in many countries and regions. To maximize the use of this valuable resource, effective beneficiation processes are required to improve recovery and grade. This article will introduce several common limonite ore beneficiation methods, including gravity separation, magnetic separation, flotation separation and combined process.

There are different types of iron ore in nature, mainly divided into magnetite, hematite, limonite, siderite, ilmenite and chromite. The mineral processing technology adopted by different types of ores are of course very different.

When purifying powdered quartz, it generally needs to be processed by mechanical scrubbing, magnetic separation, flotation separation, acid leaching and calcination to remove impurities and associated minerals. The following will introduce you to the detailed powder quartz sand separation and purification technology.

Rare earth ore beneficiation uses a variety of different methods to enrich rare earth resources to obtain high-grade rare earths. In general beneficiation, the mineral processing method of rare earth ore is selected according to the difference in properties of rare earth and associated minerals. Among them, flotation separation is the main method, and there are also gravity and leaching methods, and magnetic separation is mainly used to cooperate with the above-mentioned separation methods. The following editor will focus on the first three rare earth ore beneficiation processes.

Fluorite ore is a mineral that is easy to flotation separation. The flotation process is an important fluorite ore beneficiation method. There are some key technical parameters that will affect the fluorite mineral flotation separation effect in actual production, such as pH and temperature of ore pulp, ore particle size in flotation process, hardness of ore pulp water, flotation reagents, etc. We will discuss the influences caused by these parameters.

With the continuous development of technology, at present, the concentrator has a variety of separation technologies for copper sulfide ore, namely: rapid step-by-step priority flotation process, low alkalinity flotation process, and polymetallic copper ore flotation process. The beneficiation process of copper sulfide ore will be introduced in detail below.
