The most fundamental requirement for ore representation in ore dressing tests is that the ore samples taken and formulated are basically the same as the minerals sent to the beneficiation plant for selection during future mining. The general requirements for representative ore samples are as follows:
1. Under normal circumstances, a fully representative ore sample within the mining area of ​​the whole deposit or deposit should be taken.
2. The ore sample should be able to represent various types and various grades of ore in the deposit. Should be taken according to different types and grades of ore, so that the composition of minerals, chemical composition, structure and structure, useful mineral particle size and incarnation characteristics, associated beneficial and harmful components and the distribution and occurrence status of the comprehensive recovery of components, and the The type and grade of ore in the deposit are basically the same; the weight ratio of various types and various grades of the ore should be basically the same as the proportion of various types and various grades of ore reserves in the deposit, or should be put into operation with the mine The proportion of ore to be sent during the year is basically the same.
3. The physical and mechanical properties and chemical properties (such as density, bulk density, hardness, brittleness, compressive strength, viscosity, humidity, mud content, oxidation degree, soluble salt content, etc.) of the ore sample should be within the scope of mining Or should be consistent with the nature of the ore that was sent to the mine for a certain number of years.
4. The average grade and fluctuation of the main components of the ore sample, the beneficial beneficial and harmful components, and the content of the components that can be comprehensively recovered shall be equal to the types and grades of ores in the corresponding range of the ore deposit (or the ore is sent for production within a certain number of years). The basic situation is the same.
5. The types, compositions, and proportions of ore samples taken from the rock mass surrounding the top and bottom of the ore body and the stone should be basically the same as the actual conditions of the ore deposit.
Reasonable sampling can not only help the user to select the right magnetic separation equipment, but also determine the appropriate production process, ensure the production efficiency, and deepen the understanding of minerals. I have a prototype plant, users can do for free dressing test, welcomed the new and old customers to the factory to do the beneficiation test, order the required magnetic separator.
