Laboratory test and analysis of recovery from separation of iron sand using magnetic separator

Abstract

The iron sand mining is a prevalent practice because such a material is a mineral with many uses, including as a raw material in the iron and steel industry. In mining, iron sand certainly carries other minerals as impurity minerals. Thus the iron sand needs a further processing to increase the content of the iron itself. The widely used method is using a magnetic separator since the iron ore is a material that is strongly attracted by magnetic force. In contrast, the impurity material is repelled by magnetic forces so that the separation of iron sand from impurities can be carried out properly. The purpose of this study is to increase the content of valuable minerals available in the iron sand material. The variables used in this study includes the strong electric current and the size of iron sand. This study obtained a maximum result at a material size of 100 mesh with a current strength of 5 amperes with the acquisition of concentrates as much as 165,189 grams and a recovery value of 65,041%.
