RESEARCH OF WATER TRANSPORT IN LEACHING TECHNOLOGY

The paper studies the basic law of water transport by test when the copper is leaching under some volume of sprinkling.It may be concluded that the sprinkling of ore-column is process which the grain of ore is becoming wet and hole between the grain is becoming saturated.Controlled the proper volume of sprinkling,ore-column can keep unsaturated long,which is benefit to leaching.
