摘要
Abstract
To make the natural veins quartz come up the standard for high purity quartz sands, the purifying technology of calcination-water quenching-flotation-acid leaching-purification of alcohol -deionized water was used to obtain high purity of quartz sands. The microstructure, morphology, phase, particle size, and composition of the prepared quartz sands were determined by optical microscope, SEM, XRD, laser particle size and inductively coupled plasma spectrometers. The results show that the particle size distribution of grit is relatively uniform. The particle size of flotation and high temperature calcination fine sands is obviously increased than that of quartz grit, and the specific surface area is obviously decreased. The block matrix of fine sands after flotation is pure quartz. Screening and calcination have no obvious effect on the removal of the impurity elements, while floatation and acid leaching experiments show excellent cleaning effect. The mass fraction of SiO2 in purified samples is more than 99.99%.关键词
