With a total of 2 patents, his work focuses on reducing cyanide consumption in gold recovery processes.
Latest Patents
Winborne's latest patents include innovative methods for enhancing gold extraction from refractory ores. One of his notable inventions is a process that reduces cyanide consumption in gold recovery from finely ground sulphide ores and concentrates. This method involves pre-treating the ore with fine grinding and an initial leaching step using inexpensive limestone and lime to maintain an alkaline environment. By adding oxygen and carefully controlling the conditions, the process partially oxidizes the ground ore, allowing for a more efficient cyanide leaching step that can reduce cyanide consumption by more than two-thirds. Another patent focuses on a method for treating precious metal-bearing minerals, which involves milling the mineral composition to a particle size of less than 25 microns and leaching it with a solution containing lime and/or limestone in the presence of an oxygen-containing gas.
