Research on dosage matching for gold and antimony froth flotation based on rough sets and case-based reasoning

摘要

Currently controlling dosage in mineral flotation process is based on the subject experiences of operators, which are influenced by different operating technique. According to different shifts, process performance of forth flotation is different so that the flotation process is often running in unstable states. Lots of production data of gold and antimony forth flotation process have been acquired, which can be used to build case rules of adding dosage for the process, build the flotation process of flotation reagents adding quantity is putted forward based on a large amount of data acquried by flotation process, combining with the characteristics of rough set to dealing uncertain knowledge, the introduction of the Cauchy inequality. A new method of flotation dose matching is proposed based on rough sets and case-based reasoning., realized the control of reagent adding in floatation process. This method has been applied in a real industrial site. The application results show that the proposed method can effectively reduce the contents of tailings and improve the recovery rate.
