Progress on Study of Methods for Leaching Contaminants from Mineral Products and the Leaching Characteristics

A review on the study of methods for leaching contaminants from mineral products and the leaching characteristics products, mainly of the last decade, was presented, prospecting especially for the leaching methods, including humidity chamber test, leaching column test, static immersion test and extraction test, as well as the influential factors to the leaching amount, such as pH value, leaching or soaking time, temperature, conductivity, ratio of solid to liquid and particle size of minerals, etc. (32 ref. cited).
