The methods for water purification on a large scale are: a. Storage. Water is collected from the source and stored in natural or artificial reservoirs. Storage provides a water reserve that keeps pollution out. A significant quantity of purification takes place in storage. The optimum period of storage is 10-14 days.
Types of Purification. A large number of methods are available for the purification of substances. The choice of method, however, depends upon the nature of substance (whether solid or liquid). It also depends on the type of impurities present in it. We commonly use these methods for purification of substances: Simple crystallisation

Barite is an important strategic non-metallic mineral. China has rich barite resources. Its reserves, output and export volume rank first in the world. However the situation of low export price has existed for a long time. Based on the characteristics of barite ore at the present stage, this paper introduces the different dressing methods of barite ore in China.
4. Discussion. For the unspiked samples, the apparent S- and O-isotope values of extracted barite product (i.e., δ 34 S app and δ 18 O app) are consistent with those of the untreated barite powder (i.e., δ 34 S barite and δ 18 O barite), demonstrating that without pyrite, the extraction process itself imparts little or no isotope fractionation of …

Barite is a mineral composed of barium sulfate (BaSO4). It receives its name from the Greek ord "barys" which means "heavy." This name is in response to barite's high specific gravity of 4.5, which is exceptional for a nonmetallic mineral. The high specific gravity of barite makes it suitable for a wide range of industrial, […]
