UPGRADING OF A FLOW SHEET SELECTION PC ALGORITHM FOR REFRACTORY CONCENTRATES TREATMENT

摘要

In this paper, a computer program is proposed to treat refractory concentrates. This approach couldrnbe integrated into an expert system useful for decision support or process control. The operation ofrngold and silver-bearing concentrates treatment is largely based on the specialists experience and flowrnsheets used.rnIn order to select an optimal and economically viable flow sheet, a program based on the theoreticalrnknowledge and practice has been created. It works in a dialogue regime and was written in Borlandrnbuilder? programming media. The program allows a flow sheet for an effective treatment of gold andrnsilver-bearing concentrates to be selected by the specialists.rnEconomic aspect of selected flow sheets to the concentrates with different noble metals grade orrnwidely used hydrometallurgical oxidation procedures were not included in the first version of thernprogram. Contradictions in the recommendations produced by the program were mainly solvedrnduring its latest upgrading.rnIn case of multiple choice recommended by the program, an owner of a plant or a mine makesrna final decision based on throughput of a designed plant, ore reserves, available and affordablerntechnological equipment. Generally, a final choice can be without an alternative or is defined by twornor more alternative flow sheets. The choice of the flow sheet is based on the comparison of the resultsrnof pilot plant or scale-plant testing.rnIntroduction of an additional logical operation excluding non-profitable options facilitates thernuse of the program by owners and managers who are not specialists in the filed of noble metalsrnconcentration and metallurgy.rnThe flow sheets options for the concentrates with an industrial grade of heavy base metals arernproposed to provide for maximum complex recovery of valuables from the ores if possible.
