Such as the nickel mine further recovery from tailings of nickel, the recovery rate of nickel increased from about 50% to 90%. Copper mine tailings recovery of iron and copper, about 16.94% tons of copper concentrate can be obtained annually grade 2.56t, grade 53.5 of iron concentrate 43% tons, an annual output value of 80 million USD.
Long heavy manufacturing all the equipment of tailings recycling, decades service in the market to achieve a good reputation. Up to now, LZZG design several kinds of tailings dry row sieve, which cost less investment, and get the highest return of the system. A set of heavy LONGZHONG tailings disposal simulation system in the workshop, can simulate the tailings dry drainage treatment effect site. A lot of customers drove with the material on the spot, the effect of the test machine to make customers very satisfied.
