Drilling and mineral processing

The proportion, viscosity and thixotropy of mud are adjusted in drilling and digging well
to improve the stability of mud. In well cementation and workover, its filtration resistance
and surface conjunctivity strengthen the surface protection of well wall. As a gel polymer in
fracturing fluid, it is used to prevent fluid loss agents and drag reducing agents
In the beneficiation of ferronickel and copper zinc, it is used as an inhibitor in flotation
to improve the concentrate grade
