Nickel Sulfate

The oxidation process produces concentrated Nickel Sulfate solution in an enclosed environment. After heating and increasing the pressure in the sealed reactor, it results in the formation of blue crystalline Nickel Sulfate. The impurities of it are then removed from the crystals by treating them with a diluted solution of Barium carbonate.

Lead removal from tin chloride solution by barium sulfate and

Herein, we conduct an in-depth investigation of the specific process that the Cl − influences lead removal by barium sulfate coprecipitation. Because of the complexation equilibrium in the tin chloride solution, the Cl − concentration was bound to affect lead removal during barium sulfate coprecipitation. To determine the behaviour and mechanism of lead …

Gold Smelting & Refining Process

The Miller chlorination process is well know and has been practised for a long time in the gold refining industry. The process consists of chlorine addition into the molten Dore by using an immersed tubing system. Initially there is a slow reaction of chlorine gas with base metals forming volatile compounds.

The impact of sulfite ions on barium sulfate crystallization

This manuscript aims to investigate the impact of another sulfur containing anion on the process of barium sulfate crystallization. The rational behind the choice of this ion is that the sulfite ion is slightly stereochemically different to sulfate but has the same formal charge (see Fig. 1).One complication is that the sulfite ion can oxidise to sulfate in solution, however, this …

Barium Chloride (BaCl2): Properties, Preparation & Uses

Barium chloride (BaCl2) is an inorganic compound that can be prepared in various ways. One method involves reacting barium hydroxide (Ba(OH)2) or barium carbonate (BaCO3) with hydrogen chloride (HCl). In this process, the barium hydroxide or barium carbonate is mixed with hydrochloric acid, which results in the formation of barium chloride and ...
