  • Shaft furnace for heat treatment of finely dispersed materials
    Patent number: 4494930
    Abstract: A shaft furnace for heat treatment of finely dispersed material has a casing of rectangular cross section with a hopper built into a cover thereof. The top of the casing accommodates pipes for drawing off resultant gases. The casing also houses two groups of plates equidistant from the vertical axis of the casing and having different lengths increasing in the direction from the vertical axis toward a narrow wall of the casing so as to form therebetween and the narrow wall of the casing passages for the flow of gases toward the pipes for exhausting resultant gases.

  • Method of treating pyrite bearing polymetallic material
    Patent number: 4386061
    Abstract: A method of treating pyrite bearing polymetallic material comprises heating the material in an atmosphere of reducing gases at a temperature of 450.degree. to 500.degree. C. for a period of 30 to 60 min.Gases such as hydrogen, or products of conversion of natural gas or mazut can be used to provide the reducing atmosphere.The roasted copper-containing material is cooled at a rate of 2 to 4 deg. per min and is then subjected to magnetic separation.The operation of magnetic separation is carried out in two stages with the intensity of the magnetic field ranging from 1000 to 2000 oersted, whereafter copper sulphides are removed from the roast, with a magnetic field intensity ranging from 4500 to 6000 oersted.

  • Desulfurizing roast of pyrite bearing polymetallic raw material
    Patent number: 4368176
    Abstract: A method comprises heating the material to be treated without access of air at a temperature of 700.degree. to 800.degree. C. for a period of 1-2 hours, and then subjecting this material to subsequent magnetic separation.It is advisable that the furnace walls surrounding the material under treatment be heated to a temperature which is 100.degree. C. to 200.degree. C. higher than the boiling temperature of the volatile components of the material. Upon completion of the heating operation, the material being treated is cooled at a rate of 2 to 4 deg. per minute, whereafter iron sulphides are removed therefrom by means of magnetic separation, the intensity of magnetic field ranging from 1000 to 2000 oersted, and then copper sulphides are separated, with the field intensity ranging from 4500 to 6000 oersted.
