Mineral beneficiation tests done causes and used equipment

Beneficiation tests is the ore choose test in order have good concentrator design . Beneficiation test results not only have influence for the concentrator design process, equipment selection, product solutions, technical and economic indicators , but also the basic of whether the concentrator can successfully meet the design production and get better economic benefit. Beneficiation test is to take a small number of representative samples in the laboratory and using a small crusher, screening machine, post mill, ball mill ( rod mill ) , flotation machine, magnetic separator , jig, shaker table, spiral chute, stirred tank leaching and other equipment to do the flotation , magnetic separation , re-election , the chemical beneficiation processes .

Evaluate whether there is have business value to develop one ore for the commercial exploitation of the value of one - beneficiation tests. Therefore , the material composition of deposits in large, complex , large mineral deposits and no new ore type experiments , laboratory tests should be done to expand the scale . The industrial sector should be done semi-industrial or industrial test test when necessary. Before doing dressing experiment , geological exploration unit of ore material composition should do a study to identify the beneficial and harmful elements occurrence, identification of mineral species , ore texture and structure , dissemination size characteristics of the process to develop a reasonable test for Xuanye provide basic information .

Beneficiation test according to the purpose of the research can be divided into optional test , test and beneficiation process single technology test three types can be divided according to a pilot scale laboratory tests , semi-industrial and industrial test of three tests . To facilitate easy and clear narrative of beneficiation test requirements , summarized the two categories will be divided into optional beneficiation test type tests , laboratory tests of small processes , continuous expansion of laboratory tests , semi-industrial testing, industrial testing and beneficiation single technology test six of them.

Mineral development process, because the nature of the mineral ore minerals geographical differences, different regions are not the same, such as ore grade ore , structure , mineral form , associated beneficial mode of occurrence of harmful elements , Khenpo granularity relationships with students are unpredictable , could affect mining investment , it is not blind investment , we must do the ore samples to the laboratory test optional . In the laboratory can get qualified minerals, to determine the optimal beneficiation process .With optimal beneficiation process , you can make the concentrator design, equipment selection before purchase equipment until the equipment installation of qualified products. Beneficiation test costs less than 5% mining investment, spend tens of thousands or hundreds of thousands of test costs relative safety of mining investment is definitely worth it, and the result is a big profit .
