Patent number: 9982320Abstract: This invention describes a hydrometallurgical process for the recovery and separation of valuable elements, in particular gold and silver, from a feed material comprising a refractory, intractable or otherwise poorly responding to conventional treatment routes ores, concentrates and other materials. In particular, the process is a process integrated into one or more existing value element extraction processes.Type: GrantFiled: November 24, 2015Date of Patent: May 29, 2018Assignee: LIFEZONE LIMITEDInventors: Keith Stuart Liddell, Lisa Anne Smith, Michael David Adams

Patent number: 9540706Abstract: This invention relates to a hydrometallurgical process for extracting platinum group metals (PGMs), gold, silver and base metals from a flotation concentrate (10) containing sulphide minerals such as pentlandite and chalcopyrite, along with pyrite and pyrrohotite. The process includes a modified pressure oxidation step (12) to selectively separate base metals into sulphate medium (14), from the PGMs. The modified pressure oxidation step (12) partially or completely oxidizes sulphide minerals to produce a product slurry (14) containing base metal sulphates in solution and a solid residue containing PGMs along with sulphate and elemental sulphur. The solid residue is subjected to a thermal treatment (18) to remove sulphate and elemental sulphur from the solid residue, and to condition the PGMs to be soluble in chloride medium. The treated solid residue is the subjected to PGM recovery by leaching in chloride leaching medium (20) to recover the PGMs.Type: GrantFiled: July 12, 2013Date of Patent: January 10, 2017Assignee: LIFEZONE LIMITEDInventors: Keith Stuart Liddell, Michael David Adams

Patent number: 7435341Abstract: An oil filter assembly includes a pressure relief valve adaptable to wide variety of environments while maintaining ease of assembly and manufacture. The pressure relief valve of this invention also occupies a minimal amount of space within the filter assembly as compared to conventional valve arrangements. In the preferred embodiment, the three-piece filter system comprises a base, a deep pocket filtering media, and a housing shell. The unitary filtering media and cap member are formed as a replaceable component that seats into the housing shell without a center tube or other outside support. When the housing shell is threaded onto the base, the cap member is sandwiched between a ledge on the shell and a seal on the base. The pressure relief valve allows fluid to continue to flow in the event the filter element becomes clogged whereby the valve provides ease of assembly, reduced cost, and reduced valve size.Type: GrantFiled: October 10, 2006Date of Patent: October 14, 2008Assignee: Wix Filtration Corp LLCInventors: Brian Scott Crawford, Michael David Adams

Patent number: 7410575Abstract: A three-piece filter system comprises a base, a deep pocket filtering media, and a housing shell. The base is adapted to be fitted/threaded onto an engine block, with a sealing surface to provide a seal with the engine block. The filtering media and cap member is placed pleated-media end down into the housing shell. The filtering media self centers and the housing shell with the filtering media attached is attached to the base. The unitary filtering media and cap member are formed as a replaceable component that seats into the housing shell without a center tube or other outside support. When the housing shell is threaded onto the base, the cap member is sandwiched between a ledge on the shell and a seal on the base. The filter media itself is a solid block and has no center tube. The filter media is a solid pleated pocket design affixed to the cap member. In the preferred design, the filter element is square rather than round to increase surface area.Type: GrantFiled: May 27, 2003Date of Patent: August 12, 2008Assignee: Wix Filtration Corp LLCInventors: Brian Scott Crawford, Michael David Adams

Patent number: 6336946Abstract: A panel-type filter employs a rectangular filter element having shifted pleats wherein the peaks of the pleats on the upstream and downstream sides of the filter medium alternate between high and low peaks. By so configuring the filter medium, turbulence is decreased at the upstream side of the filter which reduces restriction. The reduced restriction increases air flow to the engine which results in reduced fuel consumption and higher engine output power. Moreover, compression and turbulence is reduced at the downstream side of the filter resulting in flow past sensors to the engine which is more laminar, thus increasing the effectiveness of the sensors.Type: GrantFiled: February 21, 1995Date of Patent: January 8, 2002Assignee: Dana CorporationInventors: Michael David Adams, David William Ager, Gregory Keith Rhyne
