In recent years, China's demand for photovoltaic glass sand and high-purity quartz sand has been increasing, and the contradiction between the gradual scarcity of natural high-quality quartz resources and the growing demand has become increasingly prominent. The key to alleviating this contradiction is to overcome the production of low-quality quartz resources. Therefore, it is imperative to strengthen the beneficiation and purification of low-grade quartz. As a tailings grinding mill manufacturer, we will introduce the method for making quartz sand from kaolin tailings below.

Kaolin tailings are solid wastes discharged after kaolin beneficiation. For a long time, kaolin tailings have been piled up in the open air as industrial wastes, occupying a lot of land, polluting the environment, and causing excessive consumption of non-renewable resources such as kaolin. In response to the call of sustainable development, comprehensive utilization of kaolin tailings, recycling and turning waste into treasure has become a hot research direction at present. At the same time, it is particularly important to protect the environment and benefit society and future generations. Since the main minerals in kaolin tailings are quartz and kaolin, the extraction of quartz sand from kaolin tailings is an important direction in kaolin recovery. The main mineral in kaolin tailings is quartz, followed by mica, feldspar, tourmaline, rutile, zircon and clay and other minerals. A large amount of quartz resources in kaolin tailings have great recycling value. The research on the purification technology of kaolin-associated quartz resources can not only improve the resource utilization of kaolin tailings, but also provide a theoretical basis for enriching the source of quartz sand.


The process of making quartz sand from kaolin tailings: take kaolin tailings for grinding, sieving, remove fine particles, leave coarse particles, and mix the coarse particles with water, flotation agent and ph regulator to make flotation material, and the flotation material is processed. Stir flotation, take the upper layer of foam, dry it, and prepare the primary treatment material; the flotation agent is composed of sodium oleate, starch and anhydrous calcium chloride according to the mass ratio (3-4): (1-2): ( 1.5-2) composition; the pH regulator used is sodium hydroxide, and the pH regulator is used to adjust the flotation material to be alkaline; the mass ratio of the flotation agent to the coarse particles is 1: (15-17); The primary treatment material prepared in the above steps is mixed with a scrubbing agent, and ultrasonically scrubbed to obtain a reprocessing material; the prepared reprocessing material is subjected to magnetic separation and drying to obtain the final product.


To make quartz sand from kaolin tailings, it is necessary to grind the kaolin tailings first, so that the particle size of the kaolin tailings is reduced and the contact area with the flotation agent is increased. This requires the assistance of a tailings grinding mill. HCMilling(Guilin Hongcheng), as a tailings grinding mill manufacturer, our HC series large tailings pendulum grinding mill, HLM series tailings vertical roller mill and other tailings grinding mill have been widely used in the deep processing of tailings. It can process 80-600 mesh tailings and provide equipment support for the production of quartz sand from kaolin tailings.
