Abstract. Granite tailings are rich in quartz and feldspar with high recycling value. However, quartz-feldspar separation usually adds sulfuric acid and hydrofluoric acid, which inevitably leads to equipment corrosion and environmental pollution. This study introduced an alkaline-based flotation method to treat granite tailings.

Ore is a term for either a native metal or a metal-bearing mineral or rock that is mined for profit. Mineral processing is the first step for ore once it leaves the mine. The process involves ore preparation, milling, and ore dressing, commonly known as beneficiation. Beneficiation mechanically separates the grains of ore minerals f…See more on steqtech

Granite ( sensu stricto) is a coarse-grained intrusive rock in which quartz is 20-60% QAP content by volume and alkali feldspar accounts for 35% to 90% of the total feldspar. It doesn't have feldspathoids. You may subdivide granite into synenogranite with 65-90% of the total feldspars alkali feldspar and mozogranite with 35-65%.
