摘要： Provided is a manufacturing method of ferromolybdenum from molybdenite concentrate, and more particularly, a manufacturing method of ferromolybdenum with copper content of 0.5% or less from molybdenite with high copper content without carrying out a separate copper removing process by putting molybdenite, aluminum metal and iron metal, in a heating furnace and reacting them at high temperature to manufacture the ferro molybdenum at the lower portion thereof, forming a slag using aluminum sulfide and iron sulfide as the main components at the upper portion thereof, and putting most of the copper (80 to 95%) existing in the molybdenite in a slag layer. The exemplary embodiment can shorten a process as compared to a metallothermic reduction (Thermit) method of the related art and reduce the consumption of a reducing agent, i.e., aluminum.

摘要： Disclosed is a method for preparing low-oxygen titanium powders. The method includes (a) separately placing titanium base powders and calcium in a deoxidation container, (b) deoxidizing the titanium base powders by heating an inner part of the deoxidation container at a temperature of 850° C. to 1050° C. so that the calcium is evaporated to make contact with the titanium base powders, (c) removing calcium oxide from surfaces of titanium powders, which are obtained by deoxidizing the titanium base powders in step (b), by washing the titanium powders, and (d) drying the titanium powders subject to the removing of the calcium oxide in step (c).

摘要： Disclosed is a deoxidation apparatus for preparing low-oxygen titanium powders. The deoxidation apparatus includes a lower container having an open upper portion and storing an deoxidizer representing an oxygen degree higher than an oxygen degree of titanium and a melting temperature lower than a melting temperature of titanium, and an upper container coupled with the lower container on the lower container and storing titanium base powders. The upper container is provided at a lower surface thereof with a sieve, and allows the deoxidizer, which is evaporated due to heating, to make contact with the titanium base powders so that the titanium base powders are deoxidized.
