Method for recovering strontium slag

The invention relates to a method for recovering strontium slag. The method comprises the following main steps: (1) adding hydrochloric acid in the strontium slag under the condition of stirring until the pH value of a reaction system is stabilized between 1 and 2; (2) adding a calcium carbonate source substance in the reaction system obtained …

Use of barium-strontium modifier for the manufacturing

The possibility of using a barium-strontium modifier as a gasprotective and refining additive for welding the fluxes based on crushed slag from the production of ferrosilicomanganese is presented.

A novel Boudouard reaction catalyst derived from strontium slag …

Strontium slag (SS) is the accessory substance in the manufacture of strontium carbonate from celestine, and plenty of it was produced in China annually [35], [36]. The storage of SS occupies land and affects the environment severely. Moreover, it causes a waste of resources for available waste residue. Therefore, the effective …

Utilization of steel slag for Portland cement clinker production

The steel slag was mixed with other raw materials, such as limestone, clay, sand, and bauxite, in appropriate proportions in order to produce the raw meal to be tested for the production of Portland cement clinker ((PC) S/S).A reference raw meal ((PC) Ref), without steel slag, was also synthesized for reasons of comparison.The chemical …
