These Processes Can Remove Impurities from Potassium Feldspar

2021-01-25 XinHai Views (77)

China's potassium feldspar rich resources are few, and often coexist with other impurity minerals, especially a small number of impurities such as iron and titanium, which affect its quality and application, so it needs impurity removal. At present, the main impurity removal methods of potassium feldspar are magnetic separation, flotation separation, acid leaching process and combined process. Specifically, the appropriate impurity removal process should be selected according to the occurrence state of impurity minerals and the embedded particle size.

At present, the common tin ore processing processes mainly include gravity separation, flotation and magnetic separation.

Five Tailings Dry Discharge Processes, Which One Is Right for You?

2020-12-18 XinHai Views (107)

The tailings dry discharge is a new tailings processing process gradually emerging at home and abroad, that is, after the tailings slurry is concentrated in multiple stages, and then processed by efficient dewatering equipment such as dewatering vibrating screen to form slag with small water content, easy to precipitate, solidify and be stacked. The slag can be transported to a fixed location for dry storage.

Break Through Carlin-type Gold Mineral Processing Difficulties, Help You Grasp The Carlin-type Gold Mineral Processing Technology!

2020-12-11 XinHai Views (96)

In various kinds of gold ores, the Carlin-type gold ore is a kind of finely disseminated gold deposit mainly produced in carbonate rocks. This gold ore relatively low, the metallogenic scale is large, and the gold particle size is fine.  The main gangue minerals include quartz, calcite, barite, kaolinite, etc., which are difficult to recycle gold mines. The harmful elements such as arsenic and mercury may cause environmental pollution if not handled properly. Next, let’s take a look at the processing difficulties of Carlin-type gold mines and their processing technology.

Common Hematite Flotation Methods and Introduction of Reagents

2020-11-20 XinHai Views (79)

Hematite, a relatively large mineral resource of weakly magnetic iron ore resources, mainly covers hematite, pseudo-iron ore, specularite, and a small amount of siderite and limonite, etc. Among hematite processing methods, flotation separation is one of the common processing methods. Compared to other processing methods, flotation can effectively extract high-quality iron ore from fine-grained materials, thus providing high-quality raw materials for steel production.

Iron Tailings Re-Processing Technology, A New Weapon for Processing Hundreds of Millions of Tons of Iron Tailings

2020-11-19 XinHai Views (65)

Usually, according to different ore properties, different tailings treatment and recovery processes will be used for iron tailings re-processing. In general, iron tailings re-processing mainly includes the process of magnetic separation, gravity separation, flotation and combined separation methods.

Common Copper Tailings Reprocessing Methods

2020-11-16 XinHai Views (117)

With the increasing of copper mining resources, copper tailings emissions increases as well. Copper tailing is made up of the fine sands from copper ore crushing and concentration. There are an amount of metal and nonmetal minerals to be reprocessed. Suitable reprocessing technology can recycle them. It has an important meaning to the comprehensive utilization of copper tailings. In actual production, different types and characteristics of copper tailings need different mineral processing methods. In this passage, we will introduce you the copper tailing physical and chemical properties, and two types of common copper reprocessing methods: vulcanization flotation and leaching.

2020-11-05 XinHai Views (87)

The tailings dry stacking is a new tailings processing method in recent years. The tailings dry stacking technology can relieve the capacity pressure of tailings pond storage, reduce the safety hidden danger of tailings pond and increase the means of tailings reprocessing, which is a kind of tailings processing technology to realize the green mine.

Mineral Processing Experiment - What Does Flotation Experiment Involves?

2020-11-02 XinHai Views (74)

In mineral processing solution, flotation has a large application. It is complicated. There are many factors influencing flotation technology, including ore characteristics, grinding fineness, slurry concentration, pharmacy system and so on. The flotation effect is closely related to these factors. At the same time, the flotation flow solutions are multiple, such as fully mixed flotation, part mixed flotation, asynchronous flotation, and priority flotation. A flotation experiment is essential to ensure the suitable processing condition, to customize reasonable flotation flow, and obtain the ideal recovery result.
