Furthermore, the leaching concentration of heavy metal lead in tailings treated by 4% Na 2 EDTA increases to 53.44 mg/L which far exceeds the standard of pollution control. Therefore, considering stabilization efficiency and dosage, TMT is the preferred agent for solidifying heavy metals in lead-zinc tailings.
gold, silver, lead and a high grade of zinc, and includes an underground concentrator plant. The challenge Minera Tizapa was experiencing several problems at their tailings dam application including frequently replacing a pair of medium service application pumps. The incumbent pumps were not secured and were frequently lost in the dam.
London — Base metal producer Central Asia Metals Ltd. expects to lose production of some 400–500 mt/week of zinc-in-concentrate and some 500–600 mt/week of lead-in-concentrate over the next month as a result of a tailings dam leak that occurred Sept. 14 at its Sasa mine in North Macedonia, CEO Nigel Robinson said.

mine tailings is increasingly studied as an option to conventional tailings dams. The Lucky Invest Concentrator is located in the Eastern Rhodopes Mountain of Bulgaria. Since 1959 lead-zinc ores are dressed. Finally, during the flotation cycle lead and zinc concentrates are …
Lead-zinc tailings used for this study were collected from a lead-zinc mine plant in Shaoguan, China. Lead-zinc mine tailings were prepared by crushing and screening the material to particle sizes below 74 μm. A representative sample of the mine tailings was pulverized to conduct the chemical and mineralogical analysis.
Evaluation of tailings from processing plants is always an important issue. Lead-Zinc ore tailings containing 3.12% Zn, 3.43% Pb, 0.71 g/t Au and 74 g/t Ag was subject to this study.
The dam was in use at the time of treatment and both tailings sludge and contaminated water were constantly being pumped into the dam. The key objectives of the project were to remove heavy metals from the water and to achieve concentrations that would enable wastewater to be reused in the floatation process to extract copper and nickel sulphides.

In the mineral beneficiation stage, the slurry often contains much water. The high water content of the tailings is likely to lead to the tailing dam accident. Therefore, in the concentrating plant, tailings concentration and dehydration is also one of the important parts.
