Background The solid waste is various solid wastes generated in the ore exploitation and washing process. 2 t-3 t of waste rock is generated per 1t of ore mined by pit mining (underground ore), and 6 t-8 t of waste rock is stripped per 1t of ore mined by strip mine. The long-term accumulation of the solid waste in the picking and selecting process forms a serious threat to the natural environment. The wastes such as the tailings, the waste stones, the coal gangue and the like piled in the open air occupy a large amount of land resources, so that vegetation coverage disappears, soil structure is destroyed, biological habitat is lost, and the regional biological diversity is obviously reduced. The physical and chemical composition of the solid waste is similar to that of the soil-forming matrix, so that the soil-like matrix can be gradually formed by natural weathering or manual intervention. The mined material waste typically contains rock debris, clay minerals, silicates and small amounts of organic matter that are similar in material source to natural soil. For example, clay minerals and carbonaceous materials contained in the gangue can improve the water retention and air permeability of the soil, and elements such as iron, calcium, magnesium and the like in certain tailings can supplement mineral nutrients of the soil. However, the formation of soil from the solid waste by natural weathering is very slow. The prior art also shows equipment for burning solid waste into soil, but has high energy consumption and can generate tail gas, and secondary treatment is needed. There is a need to develop a device for converting the accelerated weathering of the solid waste from the extraction into functional soil to realize the recycling of the solid waste from the extraction.
