尾矿库是采矿和矿物加工企业环境污染源之一。尾矿库周围卫生保护区范围内大气中的粉尘量和其它伴生的有毒元素的浓度不仅大大超过了极限允许浓度,这类粉尘和有毒元素还散发到卫生保护区以外很远的地区。产生这种现象的原因是,所堆积的尾矿是一种未粘结的土层,容易遭受风蚀。近年来,研制并改进了干滩粉尘的防治方法,该法的基础是以形成薄膜或防蚀表层的方式固结起尘表面。但是这种方法尽管经济,但尚未得到广泛的工业应用,原因是需
Tailings deposit is one of the environmental pollution sources of mining and mineral processing enterprises. The amount of dust in the atmosphere and the concentration of other associated toxic elements in the area surrounding the tailings pond not only greatly exceeded the allowable limit, but also emitted dust and toxic elements far beyond the sanctuary. The reason for this phenomenon is that the accumulated tailings are an unbonded soil layer susceptible to wind erosion. In recent years, dry dust prevention and treatment methods have been developed and improved. The basis of the law is the consolidation of the dust-generating surface by the formation of a thin film or corrosion-resistant surface layer. However, this method, although economical, has not yet been widely used in industry due to the need
