Title: Leaching process in the presence of hydrochloric acid for the recovery of a value metal from an ore
Inventor: SMIT JAN TJEERD
IPC: C22B3/04
Filed: 2005-10-20
Abstract: A process is described for leaching a value metal from an ore containing said value metal, the process including the steps of leaching the ore in the presence of hydrochloric acid so as to form a soluble metal-chloride salt in a leach solution; adding sulphur dioxide to the leach solution; recovering a metal-sulphate or metal-sulphite salt from the leach solution; and regenerating hydrochloric acid. The ore may be an oxidic base metal ore, such as a zinc oxide ore; a lateritic nickel ore, such as a saprolitic or limonitic ore; a sulphide ore or a titanium ore. The value metal is typically selected from the group consisting of Zn, Cu, Ti, Al, Cr, Ni, Co, Mn, Fe, Pb, Na, K, Ca, platinum group metals and gold. The metal in the metal-sulphate or sulphite salt may be the value metal, or may be a metal of less value than the value metal, such as magnesium. The regenerated hydrochloric acid is recycled within the leach process.

Title: Plasma electric generation system
Inventor: VANDRIE ALAN
IPC: G21B1/00
Filed: 2006-03-07
Abstract: A system and apparatus for controlled fusion in a field reversed configuration (FRC) magnetic topology and conversion of fusion product energies directly to electric power. Preferably, plasma ions are magnetically confined in the FRC while plasma electrons are electrostatically confined in a deep energy well, created by tuning an externally applied magnetic field. In this configuration, ions and electrons may have adequate density and temperature so that upon collisions they are fused together by the nuclear force, thus forming fusion products that emerge in the form of an annular beam. Energy is removed from the fusion product ions as they spiral past electrodes of an inverse cyclotron converter. Advantageously, the fusion fuel plasmas that can be used with the present confinement and energy conversion system include advanced (aneutronic) fuels.
