As an important non-metallic mineral resource, phosphate rock plays an important position in industrial production. However, due to the complex ore composition and large grade fluctuations in medium and low-grade phosphate rock, it is difficult for traditional mineral processing methods to extr...
Coal preparation aims to remove impurities from raw coal and improve the quality of coal to meet the coal demand in different industrial fields.
I. Raw coal preparation
1. Receiving coal
The coal preparation process starts with the receiving coal link. When the raw coal is gathe...
Wollastonite (CaSiO₃), as a metasilicate mineral with a chain structure, is widely used in ceramics, coatings, metallurgical protective slag and other fields due to its high aspect ratio, low thermal expansion coefficient and excellent insulation performance. China is the world's largest wollastonit...
The global mining industry is facing dual challenges: on the one hand, high-grade ore resources are becoming increasingly depleted, and the proportion of low-grade, complex-composition ores is increasing year by year; on the other hand, environmental regulations are becoming stricter and energy cost...
According to statistics, the mining industry accounts for approximately 11% of the world's total energy consumption, making it a high-energy industry. For ore processing plants, energy efficiency and consumption reduction are crucial factors for sustainable development. In the production process of...
What are the sorting standards for fluorite?
The sorting standards of fluorite are mainly determined by the final use of fluorite concentrate. Different uses have different quality requirements for fluorite concentrate. The selling prices of different levels are also different.The following are som...
MINGDER Optoelectronics - Leading Technological Innovation in the Ore Sorting Industry
In today's highly competitive market environment, various industries have increasingly stringent requirements for product quality. As an important equipment to ensure product quality, the brand selection of o...
Although my country's bauxite ore has the characteristics of high aluminum (Al2O355%-88%) and low iron (Fe2O31%-6%), it is restricted by the high natural mixed grade rate and uneven distribution of ferrosilicon impurities (SiO23%-25%). Traditional sorting is difficult to break through the bottleneck...
1. Barite: A strategic resource trapped by "impurities"
As the most common barium-containing mineral in nature, barite is like a low-key industrial all-rounder - it is not only the "well-killing guard" of oil and gas drilling, but also the "hidden champion" of high-end coatings, and the "steel barri...
As of 2024, China's calcium carbonate demand and growth show the following characteristics:
Demand continues to rise: According to China Powder Network, from 2014 to 2023, the global calcium carbonate industry demand increased from 103 million tons to 141 million tons, with a compound annual growth...
In the coal, metal mines, metallurgy, building materials and other industrial fields, the conveyor belt is the "artery" of material transportation, and its safety and efficiency directly affect the stability of the production chain. However, foreign objects on the conveyor belt (such as iron pieces,...
