INTRODUCTION TO MINERAL PROCESSING FLOWSHEET DESIGN …

CRUSHING PLANT DESIGN The number of crushing stages necessary to reduce ore to the proper size varies with the type of ore. Hard ores like gold, iron, and molybdenum ores, may require as much as a tertiary crushing. To design a good crushing plant one has to follow these three steps: 1. Crusher selection 2. Crusher layout and 3.

Tungsten Extraction Process

The Beneficiation flowsheet shown with this study is particularly adapted to the concentration of tungsten ore in small tonnages. Tungsten minerals are generally in the friable class and therefore concentrating processes are hindered by the excess amount of fines produced in the crushing and grinding steps. Special consideration must be given to the stage …
