This laboratory work presents a study of the effect of ultrafine grinding on the gold recovery of a highly refractory gold concentrate. The particle size of the concentrate was P80 = 46 µm and the main species present were quartz (28.58%), dolomite (25.63%), pyrite (20.93%), arsenopyrite (15.39%) and 112 g/t gold. After optimizing hydrated lime …
It is important to calculate it to evaluate the metallurgical performance of the gravity circuit. I think you should clean your gravity concentrate using a shaking table (e.g. gemini table). In this way you can increase the concentrate grade, Alternatively, you can use a gold pan concentrate to clean your 2 kg gold concentrate.
Gold Concentrate is created by purifying Crushed Gold Ore in one of two different crafting stations. The crafting stations come with different ratios, labor cost and time cost. The process to make Gold Concentrate also gives a byproduct of Wet Tailings which is a pollutant. Gold Concentrate is the last step in the production line for a Gold Bar.. The …
