SU37700A1 - Autoclave for smelting sulfur from its ores - Google Patents

Description

The relatively poor sulfur content in our ores determines the method of their processing, which is currently gaining a dominant position in us — enrichment of ores by flotation with subsequent smelting of concentrates. As an example of this, Shor Soo, projected by Volgoser and Gaurdak-serra, can be cited.

The task of enrichment of ores can be considered solved. It is impossible to say the same about smelting of concentrates The adopted method of smelting in autoclaves at Shor-Su is far from justifying itself, but in spite of this autoclave smelting is designed as Volga-gray. The same goes for Paurdak-Sulfur if the issue is solved in the direction of smelting sulfur concentrates of the designed factory. All this points to the extreme importance of satisfactory resolution of the smelting of sulfur concentrates.

The described apparatus is an attempt to do this. It works with the implementation of the principle of continuity of the smelting process in this way. Flotation concentrate with a moisture content of 40-50% through a special nozzle 6 under pressure of 4-5 atmospheres is fed into a special cylindrical three-chamber (46) - -

bath 1. The same nozzle is supplied with steam (water) under the same pressure. The mixture of steam and concentrate is supplied to the agitation melting section of bath 2. Here, under the action of hot steam, sulfur is smelted from the concentrates. Under the pressure of a continuously flowing mixture, this molten sulfur, mixed with waste rock, is squeezed continuously through an opening under the partition 4 into the middle compartment of the bath, where this mixture, settling, splits into two layers: the lower layer is molten sulfur, and the upper layer is empty rock, mixed with concentrated water. Layers of layers in the drawing are shown roughly dotted. A mixture of waste rock and water is poured over the tail threshold 5 into the tail compartment 3 of the bath.

When the level of the upper layer reaches a certain height, the floats (concentration valve 7 and tail valve 9) are raised, raising the valve and allowing molten sulfur to be poured into the receiver 8 through the adjusted tap, as well as the liquid water mixture of tails through its nozzle with the adjusted tap.
