摘要： The invention is directed to a process of treating waste materials, particularly petroleum cracking catalyst waste containing contaminating and/or valuable metals to decontaminate the waste and/or recover the metals therefrom which process comprises the reduction of the metals contained in the waste in the presence of a slag former such as a silica-alumina composite, a flux such as a Group IA or IIA oxide and a phosphate containing compound. The metals are recovered as metals or metal phosphides in a distinct ferrophos layer. The accumulated metals can be further processed to recover the metal content thereof. The process parallels the electrothermal process for producing phosphorus which is desirably utilized as disclosed herein to recover valuable Group VB to Group VIII metals.

摘要： Fine powder of a metal is made by vaporizing the metal in a vaporization chamber (5) mixing the metallic vapor with an inert carrier gas, and then adiabatically expanding the mixture through a nozzle (12) which preferably is a convergent-divergent nozzle. A jet flow (14) from the nozzle is very rapidly cooled by this adiabatic expansion, which quickly condenses the metal vapor in the jet flow into very fine particles. Optionally the jet flow is directed against a metal powder collecting means, which may be a collection plate (13) but preferably is a bath of oil which entrains the particles and keeps them from agglomerating together by partially neutralizing their surface activity. Thus fine metal powder with particle diameters of the order of a few hundreds of angstroms can be economically produced.

摘要： Low grade oxidic ores, such as, for example, chromite, tantalite, wolframite, ilmenite or bauxite may be beneficiated by chlorinating the ore in a fluidised bed in the presence of carbon to produce a gaseous effluent containing ferrous chloride, partially oxidising the ferrous chloride to a mixture of ferric oxide and iron chloride, condensing and then revolatilising the iron chloride, oxidising the revolatilised iron chloride to release chlorine and recycling the chlorine to the ore chlorination. The process lends itselfto efficiency of operation. The ore may be preheated by the combustion of carbon utilising also the combustion of volatiles from the calcining of the carbon. Preferably, sufficient carbon is present during the ore preheating to supply also the needs of the chlorination. Preferably solid iron chloride is volatilised in the gaseous effluent from the chlorination. Iron oxide recovered may be used as a coolant in steel making. The residual beneficiated ores may be used in the production of special steels or for other uses.
In a modification of the process values of metals other than iron such as, for example, values of boron, gallium, zirconium, thorium, titanium or uranium aluminium or silicon, may be removed from ore.
