Methods and systems for separating a first metal from a metal-containing feed stream are provided. The method can include applying solar energy, for example, by focusing one or more mirrors in one or more heliostats, to heat a metal-containing feed stream in a heating zone to a first temperature to produce a first vapor including the first metal. The first vapor can be condensed in a condensation zone to produce a first liquid including the first metal, and the first liquid can be collected. The system can include a separation unit include a heating zone in fluid communication with a condensation zone and a means for applying solar energy to heat a metal-containing feed stream disposed in the heating zone.

A molten metal filter box. The filter box includes a filter housing provided in a flow path for molten metal. A horizontal partition is disposed within the filter housing and has at least one filter receiving passage. A filter medium in the shape of a substantially flat plate is positioned within the filter receiving passage and below an inflow path of the molten metal. The filter medium includes a hole. A filter handling tool is disposed within the hole. The filter handling tool can optionally include a handle secured to the molten metal filter box to suspend the filter medium. Advantageously, the filter medium can be removed by grasping the filter handling tool and removing the filter medium.

A vortex injection system for a metal recycling furnace a delacquering chamber and a melt chamber, and a molten metal flow channel running through each chamber. The system diverts a portion of the molten metal flow through a vortex bowl, after which that portion of the molten metal flow is then returned to the main molten metal flow. The vortex bowl has an insertion port through which scrap metal and other materials may be controllably injected into the molten metal flow.

The present invention belongs to the field of titanium metallurgy, and particularly relates to a method for preparing a titanium-aluminum alloy. The technical problem to be solved by the present invention is to provide a method for preparing a titanium-aluminum alloy, including the following steps: a. adding TiCl.sub.4 and AlCl.sub.3 to a molten electrolyte in a protective atmosphere, wherein the molten electrolyte is a mixture of at least one of alkali metal chloride or alkaline earth metal chloride and alkali metal fluoride; b. electrolyzing the mixture obtained in step a; and c. obtaining a titanium-aluminum alloy through vacuum distillation of a cathode product after electrolysis. The method of the present invention can shorten the preparation process of a titanium-aluminum alloy and reduce the manufacturing cost thereof, which is of great significance to the development of titanium alloy in practice.

The invention provides a method for the recovery of a metal-containing product (M.sub.Prod) comprising: providing a composite material comprising a matrix of oxidised reductant (R.sub.O), a product metal (M.sub.P) dispersed in the matrix of oxidised reductant (R.sub.O), and one or more metal compounds (M.sub.PC.sub.R) of the product metal (Mp) in one or more oxidation states dispersed in the matrix of oxidised reductant (R.sub.O); and treating the composite material to at least partially remove the one or more metal compounds (M.sub.PC.sub.R) from the matrix of oxidised reductant (R.sub.O) to form the metal-containing product (M.sub.Prod).
