Haiwang Hydrocyclones are used in a variety of applications including classification, desliming, fines recovery, densifying and dewatering. Haiwang has collected field data from hundreds of applications, allowing process engineers to make the accurate selection of size and configuration for each application using computer simulations.
The gypsum stack was located upgradient from the plant site which included two deep groundwater withdrawal wells. The engineering team responded rapidly to alleviate environmental concerns and determined that any groundwater impacts could be effectively contained on site within the zone of influence of the plant production wells.
followed by bentonite, Grade-A helium, and portland cement. ... gypsum, helium, leonardite, limestone, marble, scoria, siliceous shale, sodium sulfate, stone (decorative and dimension), sulfur ... There was also some recovery of trona from mine water at one locality.
The addition of gypsum to the bentonite–ore system changed the flotation response significantly by improving the copper recovery from 83% to 93% and gold recovery from 64% to 85%. Meanwhile, the addition of gypsum to the ore–bentonite mixture decreased copper and gold grades throughout the flotation ( Fig. 2, Fig. 3 ).
Binding agents include sodium bentonite, sodium sulfate, calcium sulfate (gypsum), and calcium lignosulfate or combinations of these. These flaked materials will contain about 90 percent sulfur. Finely ground or molten sulfur can be added to anhydrous ammonia or to dry fertilizer during manufacturing.

Minerals and Metals. A mineral can be identified by certain physical and chemical properties, and several of these properties may be sufficient to safely identify the most suitable system of grinding, for example the Mohs hardness or the crystalline structure.
The Bentonite is mixed with the gypsum at the required ratios and then prepared as a dry powder. The moisture content of the Bentonite used in the mix varies. For this reason it is likely that the Bentonite solid is present at least than 25% of the mix.
