Title: David William Clark: Innovator in Mineral Separation Technologies
Introduction
David William Clark is a notable inventor based in Gladesville, Australia. He has made significant contributions to the field of mineral separation, holding a total of 8 patents. His innovative approaches have advanced the processes used in the mining industry, particularly in the flotation separation of valuable minerals.
Latest Patents
Among his latest patents is a process for flotation separation of valuable minerals. This process involves subjecting a milled slurry or flotation concentrate to a series of conditioning and flotation steps. One of the conditioning steps utilizes an oxidising gas, while the other employs a non-oxidising gas along with an oxidisable surface modifying reagent. This method allows for the effective separation of mixtures of valuable minerals by customizing the conditioning and flotation steps to suit specific mixed mineral ores.
Another significant patent is a method for optimizing flotation recovery. This method enhances mineral recovery processes by feeding a slurry to a conditioning step, which is then directed to a flotation circuit to recover a concentrate. The remaining slurry is either rejected as tail or processed further. The invention includes apparatus for analyzing a sample stream of the slurry, which treats the sample with an oxidising gas. Various parameters are measured to determine the flotability characteristics of the slurry, ultimately optimizing mineral recovery.
