Introduction to Leaching is the first in a series of four hydrometallurgy courses by the author, written for university students as well as practicing engineers and metallurgists. The Hydrometallurgy series covers the elementary theoretical basis of solution chemistry, the engineering aspects, and the technical applications for a large variety of raw materials, e.g. metals, oxides, sulfides, phosphates, silicates, and others. It also covers the purification-concentration steps such as adsorption on activated charcoal, ion exchange, and solvent extraction. Finally, the general aspects of precipitation from aqueous solutions are covered with numerous examples. The series is characterized by clear and simplified flowsheets, numerous chemical equations written mainly in ionic form, many illustrations for equipment and plants, and finally a lucid style presenting the facts point by point as concisely as possible. Hydrometallurgy 1 - Introduction to Leaching covers solution chemistry, leaching mechanisms and processes, leaching methods and equipment, engineering aspects and microorganisms. Solution chemistry introduces the structure of minerals and water, elementary concepts of acids and bases, oxidation and reduction, complex formation and precipitation. These concepts are included because many metallurgy students do not have this chemistry background. The rest of the course is devoted to the general aspects of leaching of ores and concentrates, the reagents used, methods and equipment, the engineering aspects, and the role of microorganisms.

In this course, we discuss the water and chemical mass balance of a mine site and the many components or facilities that go to make up a mine. There are as many water and chemical mass balances as there are mines. And there are as many mass balances as there are facilities on a mine. In this course we focus on the fundamental theories and methods and illustrate these with examples that are intended to assist and guide in compiling water and chemical mass balances for a mine and its various facilities. This course is one of a series of related courses, others in the series include: Groundwater in Mining Surface Water Management at Mines Objectives Reasons for undertaking a facility or site water balance study may include: evaluating strategies for optimum use of limited water supplies; establishing procedures for limiting site discharge and complying with discharge requirements; estimating the demands on water treatment plants, holding ponds, evaporation ponds, or wetlands.

This course is about heap leaching: the design of heap leach pads; the mechanics of preparing the mined ore for placement on a pad; the construction processes involved in placing materials on pads for leaching; the operation of heap leach pads, including the application of fluids that liberate the metals in the ore; the physics and chemistry of the seepage of fluids through the ore; and the ultimate closure of the heap leach pad when mining ends. Objectives By the end of the course you should know enough to plan, establish, operate, and close a heap leach pad. And if you choose not to do all this alone, you will have sufficient information and knowledge to retain and manage specialists, consultants and contractors, hence to undertake the activities attendant on successful heap leaching.
