Three Methods of Mining Tailings Utilization

Our technical staff said the three the most simple and feasible method of tailings management and utilization as follows:
The first is the use of the tailings to the development of building materials. Gold tailings, silica sand, sandstone, or quartz can be used. Brick is the most common building materials, tailings brick-making is also a good method of adding a certain amount of lime made of brick, and then into the carbonization chamber, which leads toCO2 carbonation into the brick will not only increase the pressure of the brick to reduce the earth destroyed, the considerable economic benefits. Tailings can also manufacture flat glass and a variety of insulation, thermal insulation, and sound insulation materials. In addition, to extract valuable metals from the tailings technology has been utilized.
The second is the use of organic waste, to take biodegradable curing of gold mine tailings dust, closed, select the appropriate seed and matrix so that the plants rapidly germinate, grow in order to achieve the purpose of vegetation use. This treatment of tailings through years of practice, and explore some experience, especially in the degradation of solidified waste selection matrix, seed selection and germination time to do a number of experiments, some have been successful. It overcomes the intensive soil, tailings shape of the drawbacks of limited governance inconvenience.
Third casing farmland. Pressure of 10-20 cm of soil in a more adequate soil areas can be used then to plant, overburden farmland, expansion of arable land, this method is applicable to the tail inks showed an inverse hump-shaped. Over the years, this approach has been affirmed. But the soil is thin due to the pressure, secondary hazards caused by dust.
