Traditionally, Barium Oxide is synthesized from the thermal decomposition of Barium Carbonate (BaCO 3). This process involves heating the carbonate, which results in the production of Carbon Dioxide (CO 2) and Barium Oxide. Alternatively, the compound can also be produced through the oxidation of Barium with oxygen.
Gold flotation. The Froth Flotation Method is means separating minerals according to their different physical and chemical properties. According to classification, the flotability of gold and silver minerals is included in the first category of natural and non-ferrous heavy metal sulfides, characterized by low surface wettability and easy flotation, …
The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents: Frothers (MIBC) is …

The froth flotation process was first patented by H. F. K. Pickard, E. L. Sulman and John Ballot in the year 1906. This was nearly 19 years after the first cyanide process patents were filed by MacArthur and the Forests. This process came into light while the scientists were experimenting with the Cattermole process. Table of Contents
