Our furnace phosphoric acid processing plant

Plant History | FMC Pocatello, Idaho

At these plants, the elemental phosphorus was processed with other chemicals to make high-purity, food-grade phosphoric acid, which is a common additive in soft drinks, and to make countless phosphate compounds, which are used in baking powder, prepared flour and refined sugar, as well as in cereals, cheeses, meats, jellies, jams and malted milk. Phosphates are also used in the manufacture …

Leaching & Recovery of Phosphoric Acid Gallium & Silver

Plant Overview The process plant utilizes drying and grinding, two-stage sulfuric acid leaching, and cyanide leaching. The phosphorus, gallium, potassium, and zinc are solubilized in the acid leach operation. The silver is solubilized in the cyanide leach operation. Gallium is recovered by solvent extraction from the phosphoric acid, while silver is recovered from cyanide leach liquors using ...
