Beneficiation test is to carry out ore selection test for the design of concentrator. The results of beneficiation test not only have a direct impact on the rational determination of the process flow, equipment selection, product scheme, technical and economic indicators of beneficiation design, but also the basis of whether the beneficiation plant can successfully reach the design indicators and obtain economic benefits after putting into operation.
Suppose that a 1000tpd copper concentrator has an annual production of 300 days, the raw copper grade α=40%, the concentrate iron grade β=80%, and the concentrate price is 4000 yuan/ton. If the recovery rate is increased by 1% after the beneficiation test, the economic benefits increased by the enterprise are as follows: (1) Increase in fine mineral yield △γ=α (ε2-ε1) /β= 40%×1%/85% = 0.47% (2) Annual increase in income =1000tpd×300 days/year ×0.47%×4000 yuan/ton =5640000 yuan/year, that is, 5.64 million yuan/year. That is to say, the enterprise only needs to do a beneficiation test, even if the recovery rate is increased by 1%, it can earn more than 5.64 million yuan per year! What if the recovery rate improved even more? Or is your ore more valuable?
We set up a special laboratory to do beneficiation experiments. The laboratory is equipped with complete mineral processing experimental research equipment and rock and ore identification equipment. It is able to conduct experimental research on complex refractory ores of various non-ferrous metals, ferrous metals and non-metallic metals. Among them, gold, silver, copper, lead-zinc ore, tungstenomodusite, ilmenite, manganese ore, magnetic limonite, hematite beneficiation technology, potassium albitite, quartz, fluorite, graphite and other non-metallic purification, various oxidation ore recovery, comprehensive utilization and other research results have been in the international and domestic leading level.
