Abstract

The invention discloses a process for preparing high-purity quartz sand by using a composite method. The process for preparing the high-purity quartz sand by using the composite method comprises the steps of 1) crushing; 2) magnetic separation; 3) pulp mixing; 4) floatation: pumping quartz sand rough concentrate pulp into a floatation column to be selected through floatation so as to prepare floatation-selected quartz sand rough concentrate; 5) ultrasonic treatment; 6) acid leaching: adding ultrasonically treated floatation-selected quartz sand rough concentrate to a mixed acid liquor to be leached by the acid, and controlling the acid leaching temperature at 40-60 degrees centigrade so as to obtain an acid-leached quartz sand concentrate; and 7) washing. According to the process for preparing the high-purity quartz sand by using the composite method, by using a magnetic separation, the floatation and acid leaching combined composite process to purify the quartz sand, the content of impurities in the quartz sand concentrate can be greatly reduced to obtain the high-purity quartz sand; and through combination of three sections of processes of magnetic separation primary impurity removing, floatation purification and acid leaching impurity further-removing, the grade of the quartz sand concentrate is obviously improved. According to the process for preparing the high-purity quartz sand by using the composite method, the grade of the obtained concentrate is high, the reagent consumption is low, the treatment amount is large, and a technical requirement on preparation of the high-purity quartz sand can be satisfied.

Description

technical field [0001] The invention relates to the field of quartz sand production technology, in particular to a technology for preparing high-purity quartz sand by a composite method. Background technique [0002] Quartz sand is a hard, wear-resistant, chemically stable silicate mineral whose main chemical composition is SiO2. Quartz sandstone is the main source of quartz sand siliceous mineral raw materials for glass, ceramics, foundry and other industries. Because quartz sandstone contains impurities such as associated minerals and cement, it must be purified by mineral processing before it can be used industrially. In recent years, the glass industry and the new energy industry have developed rapidly, and the amount of quartz sand has been increasing. There is a large gap in the use of quartz sand in the glass industry, which is far from meeting the needs of economic and social development and strategic emerging industries. The unique physical and chemical properties...
