Latest Patents

Brian Judd holds a patent for a process related to sulphide concentration. The patent describes a gravity/flotation circuit where a mineral stream, such as a flotation rougher or cleaner concentrate, undergoes a two-stage size separation. In this process, the middlings stream is subjected to flotation to recover nickel sulphide, which is sent to the final concentrate. Additionally, magnesia is rejected or depressed and undergoes gravity separation to concentrate the MgO. It has been discovered that a large proportion of the MgO minerals in the concentrate are contained in the 30 to 100 micron size fraction, and they are well liberated, making physical separation possible. Furthermore, the nickel sulphide minerals and magnesia minerals have significantly different specific gravities, which can be exploited using gravity separation equipment to achieve magnesia rejection.
