摘要

Leaching is an important way of precipitation of trace elements. It is known from the leaching experiment that the content of trace elements precipitated from coal or waste is related to their existing status and concentration in coal, it is also affected by time of leaching, temperature of leaching-liquid and its pH value. The higher temperature of leaching-liquid and the longer of leaching are, the higher precipitation concentration of trace elements will be. In the cause of leaching, pH value of leaching-liquid changes, and the different trace elements are differently effected by pH value.
