Technical Field
The invention belongs to the field of copper smelting, and particularly relates to a treatment method for flash smelting of copper matte.
Background
In the flash smelting and flash converting process, the matte produced by the flash smelting furnace is used as the raw material of the flash converting furnace for continuous treatment. The matte melt produced by the flash smelting furnace is water quenched and granulated, conveyed to a stacker by a belt conveyer and unloaded into a matte storage yard, after part of water is filtered out, the matte melt is taken by a material taking machine and is led to a flash converting process by the belt conveyer.
Flash converting furnace has strict requirements to the matte quality, when the matte quality is not good, can cause the furnace conditions of flash converting furnace to fluctuate, and especially matte silica content too high can lead to flash converting furnace to put the copper bar sediment difficulty, can cause flash converting furnace to stop production when serious. Therefore, the copper and silicon dioxide content of the water quenched copper matte can be detected after the copper matte is quenched, and the unqualified copper matte with large quality fluctuation can be stacked separately from the qualified copper matte, so that fluctuation in the flash converting process is avoided.
When the flash smelting furnace is started and stopped or the furnace condition fluctuates, part of unqualified copper matte is inevitably produced, when the output of the unqualified copper matte is too large or the quality is very poor (the copper grade or the content difference of silicon dioxide is larger than that of the qualified copper matte), the unqualified copper matte is required to be separately stacked in batches according to the quality of the copper matte, a copper matte stacking site and a temporary stacking site are fully stacked with the qualified or unqualified water quenched copper matte, no enough space is available for continuously storing the water quenched copper matte, and the supply of the copper matte in the flash converting process is influenced, so that the flash smelting and flash converting operation cannot normally produce.

and other water-quenched copper matte is unqualified copper matte, and the treatment is carried out in the following way in the conveying process:
(1) copper content of Water-quenched copper matte<66% or>72% or a silica content of 0.4%<SiO2When the concentration is less than or equal to 0.6 percent, the batch of water-quenched copper matte is conveyed to a qualified copper matte storage yard and is uniformly paved on the surface layer of the qualified copper matte storage yard;
