·X ray fluorescence XRF sensor based ore sorting enables efficient beneficiation of heterogeneous ores while intraparticle heterogeneity can cause significant grade detection errors leading to misclassifications and hindering widespread technology adoption From the results above for copper ore XRF sorting classification model it is
·Beneficiation for copper ores usually includes complex four stage flotation gravity separation or both; Sulphidisation followed by flotation is the preferred beneficiation technique for oxidized
·Complex and non sulfide lead zinc ores are difficult to concentrate but the growing demand for lead and zinc metals necessitated their beneficiation Froth flotation is practically the most effective method in their beneficiation when optimum flotation conditions are attained The aim of the current study is to use process mineralogy as a tool to understand the
In this study an attempt was made to recover copper from AbuSwayel deposit A reverse flotation technique was applied leading to flotation of the accompanying oxide and sulfide minerals and gath ering copper oxide minerals in the sink product The results showed that the application of such tech nique is possible under the optimum flotation conditions Studying the main factors
