Latest Patents

Salter's latest patents focus on the "Separation of polymetallic sulphides by froth flotation." This invention introduces a new depressant composition that enhances the separation of valuable metal concentrates, including copper, nickel, zinc, and lead, from polymetallic and massive sulphide ores. The depressant is created by dissolving a mixture of quebracho and dextrin or guar gum in an aqueous solution. A water-soluble salt of lignin sulphonate is then added to this solution. The resulting aqueous polymer is further mixed with various inorganic reagents, such as water-soluble cyanide, metal sulphates, and water-soluble sulphites. This innovative depressant is utilized alongside conventional flotation reagents during the mineral separation process.
