Talking about mineral beneficiation test and test

The beneficiation test is to take a small amount (usually about 50 kg) of representative samples from the ore deposit in the mine. The laboratory uses small crushers, sieving machines, ball mills (rod mills), flotation machines, magnetic separators, jumpers The flotation, magnetic separation, gravity separation, and chemical beneficiation process tests are performed on equipment such as a jigger, a shaker, a spiral chute, and an leaching and stirring tank.
The beneficiation test is divided into three categories: beneficiation test in prospecting and exploration work, beneficiation test before the design of the beneficiation plant, and beneficiation test on the production site.
Ore dressing test is one of the important basis for evaluating whether the deposit has commercial mining value. Therefore, ore selectivity tests should be carried out in the detailed investigation and the initial stage. For large and ultra-large ore deposits with complex mineral composition and new ore types without ore dressing practice, laboratory scale-up tests should be conducted. The industrial sector should also conduct semi-industrial or industrial tests when necessary. Before conducting the beneficiation test, the geological exploration unit should do a good job of studying the ore material composition, find out the beneficial and harmful element occurrence status, identify the mineral type, ore structure and structure, and the embedded grain size characteristics, and provide basic data for the development of a reasonable process flow .
In the process of mineral development, due to the regional differences of minerals, the properties of minerals and ore in different regions are different, such as the original ore grade, structure and structure of the ore, the form of minerals, the occurrence status of associated beneficial and harmful elements, the grain size, and the continuous relationship. They are all unpredictable and may have an impact on the investment of the mine. Therefore, you cannot invest blindly. You must take samples to the laboratory for optional tests of the ore. It is definitely worthwhile to spend tens of thousands or hundreds of thousands of experimental fees on the safety of the mine investment, because qualified mineral products can be obtained in the laboratory to determine the best beneficiation process. With the best beneficiation process, the design of the beneficiation plant can be carried out. After the equipment is selected, the equipment is purchased until the equipment is installed and commissioned to produce a qualified product. The dressing test fee is less than 5% of the mine investment, and the result is a profit.
( 2 ) What is the analysis of minerals?
The mineral test is to take a small amount (usually about 100g) of representative mineral samples in the laboratory to analyze the element content in the ore with chemical instruments, high-end physical and optical instruments and other equipment. Steps of ore laboratory analysis: raw ore spectrum semi-quantitative analysis (qualitative), chemical multi-element analysis (quantitative), X -ray diffraction analysis, phase analysis.
Laboratory analysis is the eye of mine mining and production. The guidance is of great significance, including: 1. geological exploration; 2. mining; 3. production control of the plant; 4. ore trading.
In general, mineral investors first perform mineral tests. The test sheet in their hands only contains analysis data of several major elements, and the content of some harmful elements has not been done. Such a test report is not enough to evaluate the entire mine. Therefore, it is suggested that the majority of mineral investors should first understand the mining indicators and quality standards of related minerals when buying and selling mines and ores.
Finally, I hope that this article can play a certain role in the process of mining investment for friends who are developing mineral resources or who will enter the mining industry in the future.
