Especially the initial processing step requires temperatures of up to 1000 °C. An accumulation of the spodumene by reduction of the waste rock content in the initial feed is therefore crucial for the optimisation of energy and chemicals consumption during the process. Common minerals accompanying spodumene in deposits are feldspars and quartz.

Introduction to Mineral Processing or Beneficiation
12-01-2018· Most rock deposits contain metals or minerals, but when the concentration of valuable minerals or metals is too low to justify mining, it is considered a waste or gangue material. Within an ore body, valuable minerals are surrounded by gangue and it is the primary function of mineral processing , to liberate and concentrate those valuable minerals.
Rock and Mineral Texture: Controls on Processing - MinAssist
These factors will play a major influence on the process flowsheet developed for an ore, from mining strategy through to blending, processing, target grade and recovery, and tailings management. Understanding these will aid the processing engineer when trying to unlock the maximum value from the rocks, with the minimum of effort, cost and environmental impact.
