Latest Patents
One of Yu's latest patents is a method for the recovery of gold using autoclaving. This gold recovery pretreatment process is designed to extract gold more completely from refractory sulfidic ores that contain large quantities of metal carbonates, such as dolomite. The process involves treating the ore in an autoclave under elevated temperature and oxygen overpressure conditions, along with the presence of soda ash or other alkaline materials. This method allows for the oxidation of sulfidic compounds in the ore, making it more amenable to subsequent conventional gold extraction techniques. Another significant patent involves the production of metals with low selenium contents. In this process, selenium is precipitated from solutions containing metals like nickel, cobalt, copper, and others by adding chromous sulfate to the solution.
