The Relationship Between Production And Commercialization Of Mineral Products An Optimized Computer Programme

The requirements of metals by modern society have created big challenges for mining engineers minerals processing engineers, metallurgical engineers and economists to produce these metals economically from mineral deposits which contain, with time, less and less value. The advances of science and technology allow, today, the exploitation of mineral deposits which only few years ago would not have been considered economical. However, there are limitations both on the minimum grade of recoverable values contained in the ore to be fed to a mill or on the concentrate to be smelted, and on the maximum content of "impurities" i.e. chemical elements which are difficult or expensive to refine from the ore, from the concentrate or from the metal. It is also known that the cost of treatment in a mill or in a smelter, for unit of metal contained in the ore or in the concentrate, increases as the grade of the recoverable values contained in them decreases and also if the content of impurities increases. In order to work a mineral deposit economically it is necessary to ensure not only that it has more than a minimum content of values, less than a maximum content of impurities and that there exists a good up-grading or metallurgical process but also to ensure that the opti-
