What are the contents of the mineral processing experiment and the sampling needs?

Ore properties

1. Perform spectral analysis, multi-element analysis and X-ray diffraction analysis on the ore to ascertain the beneficial and harmful elements of the ore.
2. Perform phase analysis on valuable and harmful elements in the sample to provide guidance for the process.
3. Physical properties such as hardness, true density, loose density, and grindability of the sample were measured.
4. Perform rock and mineral identification on the sample grinding light and flakes, and study in detail the material composition, structure, structure and symbiosis of the ore. Study the distribution state, particle size, and embedded form of beneficial harmful elements in ore, for the process
The determination provides guidance.

Process test research

5. Conduct a test on the sample in terms of grinding fineness, dosage type, pharmaceutical conditions, dosage of the drug, etc., and determine a reasonable and feasible test plan.
6. Carry out detailed process condition tests on the determined test plan, determine the best process conditions and the most economical and reasonable process flow, and conduct open circuit and closed circuit tests to provide various test indicators.
7. Comprehensive recovery of valuable elements that have reached comprehensive recovery.

other

8. Product quality inspection of concentrate products
9. Conducting sedimentation test of concentrate and tailings to provide basis for designing equipment selection.
10. Provide simple economic benefit accounting and cost analysis data.
11, to provide the final test report, the test report can study for the construction of mineral processing plant design, write to
The quality of the report provides the basis for the report.
12. The ore dressing test time is generally 25 to 45 days, and is negotiated under special circumstances.

Sample preparation

1, provides a representative sample of not less than 200 kg, according to gold ore samples disseminated gold and uniformity of particle size where 500 kg or even require more samples.
2. If there are multiple veins (bands, points), each mine point needs to be sampled separately, and each spot is guaranteed to be no less than 50 to 100 kg.
3. All samples were processed by the researchers and the rock identification samples were picked. If the sample is simply processed, the rock identification sample should be sampled separately, not less than 20.
4, the commonly used sample method for the groove to take, and pay attention to the groove spacing and layout position.
5. Samples of different ore properties should be taken separately and should not be mixed. Such as oxidized ore and primary ore are taken separately.
6. High-grade and low-grade samples should be taken. It is not possible to use only rich ore. If the ore properties are known, 50 to 100 kg of surrounding rock samples can be taken separately for researchers.
7, the sample to follow the principle: has a certain representative, from the grade, the nature can represent the mine's overall ore.
8. The sample is best taken by technical personnel from the three aspects of geology, mining and mineral processing to avoid unilateral operations.

Data preparation

9. Provide detailed sampling instructions to clearly express sample number, weight and other information.
10. Provide key distribution ratios and ore grade requirements (multiple applications are applicable).
11. Provide detailed reports on mine geology or detailed information on mine sites. The most important data include reserves of various mines, daily mining capacity, grade, ore properties.
12. Time requirements for the test project.
13. Existing research materials.
