Heavy Machinery Mining Machinery: Do you really understand the mineral processing test?Date:2017-02-13 Views:0

The beneficiation test is an important part of the overall service provided by the heavy machinery, which is an important technical basis for the construction and production of the concentrator. Heavy weight Machinery to provide the mineral processing test services, in the depth, breadth and accuracy to fully meet customer needs.

For heavy heavy machinery, the implementation of good mineral processing pilot work, is to provide customers with design services, transformation services, resource evaluation, and many other, multi-level election Mine service important technical basis; for customers, to carry out the corresponding mineral processing test, is a reasonable investment in the development of mineral resources, to avoid the risk of technology is not Methodology.

So, how much do you know about the dressing test?
Below you will have a more comprehensive understanding of the beneficiation test through a dialogue with the Heavy Machinery Laboratory Instructor.


A: We found at work that some customers think that the test work is not so necessary, how do you think of such a problem?
A: Indeed, some customers will think that the test is not important, no need, and even resistance to mineral processing test, perhaps taking into account the cost of the trial, may have its Its consideration. I think that we first need to have an objective understanding of the role of mineral processing. That is, the test is to get the most ore treatment Good process and sorting indicators of the important, the only way. Mineral processing as a kind of project can indeed be developed from the same type of ore
, The same size of the election plant, etc., made a lot of experience. But the natural endowment of the ore, the mining area of the geographical area for the customer's craft

And product solutions are not the same, so this reference is limited, the market will often appear "plant is put into operation the day when the transformation"Case.

Therefore, in a scientific, objective and responsible attitude, heavy machinery in providing services to customers, especially the overall service plant, recommended for customers Of the beneficiation process, the test staff in the completion of the corresponding experimental study, carried out a detailed program after the comparison given.

Therefore, it is recommended that you rely on experience to judge at the same time, recognizing the scientific nature of the trial, the need to avoid technical risks, reduce operations Cost, improve the yield have a positive positive effect.

A: before the test, we generally need to provide customers with the amount of ore?
QZ: The amount of ore used for the test, depending on the type of ore, the size of the test, the required amount is not the same. For laboratory scale exploration

Test, in addition to individual mineral industrial grade itself is very low, the ore and more control in the range of 30-50kg.

A: The amount of ore is not small, why do you need so many minerals?
QZ: Because in the experiment, a conditional test would require about 3-5 test points, each point of the test requires a sample volume of 500g or 1000g, and

A complete experimental process has a number of conditions, so the completion of a system of the test, the amount of mineral demand is relatively large.

A: Do you have any suggestions for sampling in order to ensure the representativeness of the ore sample?
QZ: In the process of customer sampling, the need to pay attention to the following aspects:

Number of sampling points The number of sampling points should be as much as possible, but also take care of the construction conditions. An industrial grade or natural type of sample, sampling point can not Less than 3 to 5;

Sampling point arrangement Should be based on the comprehensive study of the geological geology of the deposit, mainly based on the requirements of the sample to determine. Should be chosen to fully represent the part of the study Sub-ore characteristics and the original quality of the exploration project and a better location as a sampling point, but also to take care of the construction and transportation conditions; should make full use of Some exploration works (tunnel or drilling core) sampling, try to avoid digging a special sampling project;

Effective control of sampling points Should select the ore industry grade and the most natural type of the most complete exploration works as a sampling project, so that you can in less sampling works Layout of a larger number of sampling points to reduce the amount of sampling works; sampling points should be roughly evenly distributed in the ore body of the various parts, not too concentrated. Along the mine The direction of the body should be sampled at both ends and in the middle, along the oblique direction in the surface, shallow and deep should also have sampling points. But when the ore body is very large, already As mentioned above, the problem of staging should be considered, that is, the sampling points should be mainly arranged in the front mining area;

Because the customer needs to be responsible for the representation of the ore sample, in general, in order to ensure the representation of the ore sample, we recommend that the customer hire a professional Personnel to operate.

A: So, what do we usually do in the tests that we usually do?
QZ: Typically, a system test will include ore properties, mineral processing technology test and other parts. Among them, the ore properties of the main study

Yes, ore spectrum semi-quantitative analysis of ore, multi-element analysis, rock and mineral identification, particle size sieve, ore grinding work index or grinding degree determination, ore Physical properties of the determination of the main content of the beneficiation process test, including: process comparison test, sorting the operation of the conditions of the test section, the whole process Open and closed road test, mineral processing products inspection, pharmaceutical cost analysis.

A: Under normal circumstances, how long do we have to complete a test cycle length?

QZ: Typically, a system test will include ore properties, mineral processing technology test and other parts. Among them, the ore properties of the main study Yes, ore spectrum semi-quantitative analysis of ore, multi-element analysis, rock and mineral identification, particle size sieve, ore grinding work index or grinding degree determination, ore

Physical properties of the determination of the main content of the beneficiation process test, including: process comparison test, sorting the operation of the conditions of the test section, the whole process Open and closed road test, mineral processing products inspection, pharmaceutical cost analysis.

Into the heavy heavy machinery laboratory
The beneficiation test work is carried out by the Heavy Machinery and Mineral Processing Research Institute, which is composed of two departments: mineral processing laboratory and mineral processing laboratory. At this, The technical staff can be more than 70 kinds of minerals for mineral processing experiments, and provide a reliable mineral processing program.
