Novel short-process continuous copper smelting device and technology

Abstract

The invention provides a novel short-process continuous copper smelting device and technology. The novel short-process continuous copper smelting device is composed of two fire refining furnaces, twoslag smelting furnaces and a multicomponent furnace, and all the furnaces are connected through sulfonium guiding pipes; the multicomponent furnace is located in the middle, and the fire refining furnaces and the slag smelting furnaces are arranged at the two ends of the multicomponent furnace correspondingly; all the furnaces are rotary horizontal cylinder-shaped furnace bodies and supported on afoundation through two supporting rollers, one of the supporting rollers is provided with a motor, and a gear drive mode is achieved; and the furnace bodies are arranged in the state of rotating around the axis, shells of the furnace bodies are made of steel plates, the furnace bodies are lined with refractory materials, and spraying guns are arranged at the bottoms in the furnace bodies. The novel short-process continuous copper smelting device and technology have the advantages that a large quantity of manpower and material resources are saved, the investment is low, and economic benefits are high; and the structure is simple, design is reasonable, the energy-saving and environment-friendly effects are achieved, and the great using and promotion value is achieved.

Description

technical field [0001] The invention relates to the field of nonferrous metallurgy, in particular to a novel short-flow continuous copper smelting device and process. Background technique [0002] The copper smelting process under the existing technology, from the concentrate to the anode plate, is completed in three stages of smelting, blowing, and refining, such as flash smelting, top blowing smelting, Noranda side blowing smelting, Vanyukov smelting, etc. . These smelting technologies have not broken through the limitations and deficiencies in the field of nonferrous metallurgy, which are mainly manifested in: large production scale, long process, large investment, low direct recovery rate of the system, resulting in loss and waste of some resources. At the same time, because the blowing and refining are carried out separately in different furnaces, the utilization rate of sulfur is low, the heat loss is large, and the SO 2 The flue gas escapes at low altitude, and the ...

Problems solved by technology

[0003] On the other hand, the current treatment of smelting slag mainly includes electric depletion process and flotation process. The production power consumption of the electric depletion process is high, and the waste slag after depletion has high copper content, high production cost, and serious waste of resources.

The flotation process is mostly used. The flotation process includes slow cooling, crushing, grinding, thickening and flotation. The flotation process is lengthy and occupies a large area. More importantly, the zinc, lead, Valuable metals such as antimony enter the slag tailings and are not recycled, resulting in a huge waste of valuable resources; moreover, the beneficiation agents added in the flotation process and various heavy metals in the slag itself will cause potential environmental pollution.
