Kaolin is a kind of non-metallic mineral, mainly composed of kaolinite, mica. Composed of residual feldspar and quartz, it is a clay and clay rock dominated by kaolinite clay minerals. The main composition of kaolin is mainly silicate minerals containing aluminum. The particles are delicate and white. What effect can industrial sodium hexametaphosphate be added when the slurry is desanted?
Weathering residual kaolin deposit is the main type of kaolin deposit, which has a high sand content. Generally, it is necessary to remove sand and only retain the soil in it when using it. Using industrial sodium h6-metaphosphate as dispersant can play a good role in the separation of soil and sand and avoid the waste of resources.
At present, the process of sand removal generally adopts the method of slurry desanding, adding the dispersant to the slurry, so that the soil and sand in kaolin ore can be separated more quickly and efficiently. The sand is removed by gravity, and the kaolin slurry is obtained. The dispersant mainly used is industrial sodium hexametaphosphate, because industrial sodium hexametaphosphate separation effect is good.
The specific operation steps of using industrial sodium hexametaphosphate to remove sand from kaolin slurry are as follows:
1. Preparation of slurry: kaolin raw ore mixed with water, adding alkali solution to adjust pH value, kaolin slurry;
2 preparation of dispersant: industrial sodium hexametaphosphate and sodium silicate added to water, mixed to get a compound dispersant;
3. Slurry: the use of industrial sodium hexametaphosphate compound dispersant added to kaolin slurry, after mixing slurry;
4. Sand removal: the quartz sand in the dispersed pulp is removed under the action of gravity, and the kaolin pulp after sand removal is obtained.
The industrial sodium hexametaphosphate produced by Shandong Jufu Chemical Technology Co., Ltd. is produced by thermal process, with less impurities, stable quality and less dosage.
