The zinc- lead test for the wet smelted waste produced by the plant was carried out.
The acidic metallurgical slag, clay and serious oxidation, mineral thinner, -500 mesh (0.03mm) 90% of the slag containing 0.25% copper, 3.40% Pb, Zn 7.43%, Au0.70 g / t Ag 164.6 g / ton. The minerals available for comprehensive recovery are lead, zinc and silver.
In the past month's test, the tester conducted a multi-program test comparison of the slag, but failed to achieve the intended purpose and analyzed the reasons. First, the smelting slag was subjected to wet smelting, and the useful minerals were subjected to various chemicals, and the target minerals occurred. Qualitative change. Second, the smelting slag is fine -0.03mm accounted for 90%, the mineral particle size is finer, it will increase the consumption of chemicals, reduce the selectivity, and hinder the mineral floating. If the advance off the mud, sludge is always accompanied by a large number of metal loss in the slime; Third, the nature of lead-zinc ore smelting slag is not clear, Pb, Zn disseminated grain size and mode of occurrence are affecting mineral sorting.
in conclusion:
1. The wet smelting slag in a certain area of ​​Shaanxi has been tested by multiple schemes, and the test results are not satisfactory.
2. Since the smelting slag has a fine particle size, the conventional re-election method has no effect.
3. Since the slag is smelted by wet method, its minerals are tested by conventional chemicals, indicating that its floatability is extremely poor, so several flotation schemes have not reached the ideal index.
4. Exploring the experiment through conventional mineral processing shows that it is relatively difficult to recover useful minerals from the smelting slag.
5. If you want to make full use of this resource, it is recommended to do a detailed study on the ore properties of the tailings.
