Wollastonite processing plant is used for wollastonite powder manufacturing. These wollastonite powders are used as filler of glaze, plastic, rubber, papermaking and raw materials of ceramics, paint. Wollastonite powder processing flow chart. Wollastonite mine ore → coarse crushing → fine crushing → grinding → fine grinding → Processing.
The open-pit mining process of wollastonite is generally similar to that of limestone mines, and medium-sized mines are more formal. Taking the iron-mercury mountain wollastonite in Lishu County of Jilin Province as an example, the ore and surrounding rock are dense and hard, and the stability is good.
Wollastonite (CaSiO3) is the most researched and well-defined mineral in the field of CO2 mineralization, but it is also a sought-after process mineral and thus, not easily justified for large scale ex situ carbon sequestration, which requires an energy-intensive step of comminution to increase reactivity. Wollastonite-rich mine tailings are …
