    Abstract: The present technology provides an illustrative apparatus for recycle electric arc furnace (EAF) dust and method of use related to the same. The apparatus has a heat controlling region coupled to a separation volume and includes at least one magnet and a cooling region. The heating controlling region operates at a temperature sufficient to transform at least some of the EAF dust into a mixture of gaseous zinc and one or more additional metals. The magnet separates the iron-rich material from the mixture of gaseous zinc and one or more additional metals and the cooling region condenses the gaseous zinc.

    Abstract: The invention discloses a reduction apparatus having a main body made of silicon carbide-based material and collectively formed by a top portion, a bottom portion, and a side portion, wherein the bottom portion includes a slanted plane, and the main body has an inlet and a metallic vapor exit provided near the top portion and an outlet provided near the lowest end of the slanted bottom portion; an inlet closure connected with the inlet; an outlet closure connected with the outlet; and a metal collector or a condenser connected with the metallic vapor exit. The invention solved problems found in conventional reduction retorts, including: small capacity, low metal output, inconvenience in charging reactant material and discharging spent residue, and heavy workload for workers. The invention also shortened the time for reduction reaction, increased production efficiency and output of the reduction furnace, and reduced production cost. The invention can be used in production of metal such as magnesium, strontium, zinc, and beryllium by vacuum smelting reduction process.

    Abstract: A 99.99% pure indium feed is charged into a crucible and heated to 1250 ° C. by an upper heater in a vacuum atmosphere at 1×10−4 Torr, whereupon indium evaporates, condenses on the inner surfaces of an inner tube and drips to be recovered into a liquid reservoir in the lower part of a tubular member, whereas impurity elements having a lower vapor pressure than indium stay within the crucible. The recovered indium mass in the liquid reservoir is heated to 1100° C. by a lower heater and the resulting vapors of impurity elements having a higher vapor pressure than indium pass through diffuser plates in an upper part of the tubular member to be discharged from the system, whereas the indium vapor recondenses upon contact with the diffuser plates and returns to the liquid reservoir, yielding 99.9999% pure indium, while preventing the loss of indium.
