Application status of barite powder in various countries

作者: 點(diǎn)擊:1849 發(fā)布時(shí)間:2021-03-24

Facing the problem of reducing non renewable mineral resources such as dolomite sand; Energy conservation and environmental protection will be the focus of future development; Barite processing and tailings recycling are also the main development direction in the future. Let's look at the application of barite powder in various fields

First, it is the economic giant America; The United States is the world's Barite producer and consumer. Before that, barite powder was mainly used as petroleum. And the weight increasing agent of natural gas drilling mud. At present, the problem of comprehensive recovery and utilization in the process of mineral development has become increasingly prominent.

Next, let's talk about the current situation of barite powder in China; In the exploitation of barite in China, township enterprises play a leading role. Because they all use local mining methods, the technology is backward, the management is chaotic and the waste of resources is very serious. With the further tightening of the policy, it will inevitably cause the popularization and attention of resource reuse and environment-friendly processing methods.

It can be said that the application of snow white in the United States and China is the embodiment of the majority. Only by making rational use of various resources, can we make all kinds of resources, especially barite, more and more scarce and serve human beings for a long time.
