State of art in copper hydrometallurgic processes control

摘要

A review of the state of art and trends in automation and control of hydrometallurgic processes is presented. Besides the great expansion of hydrometallurgic processes world-wide, there is a number of unsolved problems related to lack of instrumentation, lack of process knowledge, odd operating practices, and in general lack of use of data management and processing. In general, proceess control of local objectives are frequentl achieved, however, application of mature and new techniques, successfully adopted in other mineral processing plants, are seldom reported. In a near future it is expected that intelligent techniques will be incorporated to solve a large variaty of problems.
