Heap leaching. Computer simulation as an alternative technology

Abstract

The article discusses the possibility of reducing environmental risks and resources by finding ways to optimize technology solutions with a computer program that simulates the heap leaching process. It is shown that the main role in the design and operational control plays simulation and an understanding of the structure and movement of the concentration fronts of substances - leaching participants within the heap. The examples of process control by conventional technological parameters - density of irrigation, fineness crushing or agglomeration bulk and height of the heap - show the attainability a significant reduction in of leaching time and as a result, reducing consumption of energy, water and sodium cyanide. The latter is a major threat to the environment.
