ABSTRACT:
A clean refractory metal sponge fines product is made from refractory metal sponge fines free of refractory metal oxides, carbides, nitrides and binary iron alloys; silicon carbide, oils, greases and organic compounds; salt; dust; dirt; pieces of iron, iron alloy and tungsten carbide; and light contaminants. The sponge fines are vigorously washed and rinsed with a displacement wash to remove the bulk of the wash fluid and subject to a counter-current wash to yield clean refractory metal sponge fines. The clean sponge fines can be pressed into briquettes and sintered at elevated pressures, or mixed with an alkali metal refractory metal halide slat, pressed at elevated pressures into sponge fines/salt briquettes and dried or pressed into briquettes, dried and packaged, or pressed into briquettes and stored wet. The briquettes are non-pyrophoric.
