Geotechnical Properties of Mine Tailings

The engineering properties of tailings are important for the safety evaluation and engineering design of tailing dams. In the present study, laboratory experiments were performed to investigate the geotechnical properties of four different tailings, including two iron tailings (coarse and fine) and two copper tailings (coarse and fine).

Efficient Removal of Sulfur Dioxide from Flue Gas through

In recent years, the utilization of copper tailing and removal of sulfur dioxide (SO2) have become the focus of research. In this study, copper tailing was used as an iron ion donator to remove SO2 from flue gas. To improve the desulfurization performance, the additive was selected from metal sulfates, such as ferrous sulfate, ferric sulfate, manganese sulfate, and scrap iron. A series of

CONTROLLED RIVERINE TAILINGS MANAGEMENT

Concentrating is done using a flotation process. Two kilograms of lime per tonne of ore are added to the slurry to increase the pH to a level that allows the flotation reagents, added to a concentration of approximately 100 parts per million, to work efficiently. Air is injected into this slurry in a series of tanks. The copper
