It evaluates existing purification technologies, such as acid leaching, ultrasonic acid washing, chlorination roasting, and calcination water quenching, highlighting the limitations of current approaches in processing quartz minerals.
Acids commonly used for acid leaching include sulfuric acid, hydrochloric acid, nitric acid and hydrofluoric acid; and reducing agents include sulfurous acid and salts thereof. It has been found that the above acids have good removal effects on non-metallic impurity minerals in quartz.
Oxalic acid is another acid used for acid leaching of quartz, which is a dicarboxylic acid and a medium-strength organic acid, whose chemical formula is HOOC-COOH. Oxalic acid dissolves iron (III) oxide-hydroxide films on the surface of quartz particles faster than hydrochloric acid and sulfuric acid and produces more stable chelating ions.
Future research directions may involve extensive mechanistic analysis and kinetics studies to enhance our understanding. In conclusion, the ultrasonic-assisted acid leaching process represents a potential high-purity quartz purification method with advantages in enhancing quartz purity and reducing energy consumption.
In general, after scrubbing, desliming, magnetic separation and flotation, the purity of quartz sand can reach 99.3%-99.9%, which basically meets the demand of industrial sand. Acid leaching is the use of quartz insoluble in acid (except HF), other impurity minerals can be dissolved by acid, further purification of quartz.
Zhang et al. used phosphoric acid as the leaching agent for quartz sand under the conditions of 80 °C temperature, 10% solid-to-liquid ratio, quartz sand with a particle size of less than 100 mesh, and leaching for 120 min. It is worth noting that the addition of organic acids had unexpected effects on impurities like Al and Fe.
