Congo gold and copper smelting furnace
Equipment use description:
Copper smelting furnace is a kind of key equipment used in copper
smelting process. It is heated by electric energy to melt copper
bearing charge into crude copper, copper matte or other copper
products in the furnace.
Working principle:
The working principle of copper smelting electric furnace is based
on the electric heating effect. When the current passes through the
electrode, there is an arc between the electrode and the charge,
and the high temperature of the arc makes the charge melt. At the
same time, the resistance of the charge also generates heat, which
further facilitates the smelting process. In the smelting
process, the copper element in the charge reacts with other
components to form crude copper, matte, slag and other products.
High efficiency:
1.Electric furnace copper smelting has the characteristics of high
heat utilization rate, can quickly melt the charge.
2. Environmental protection: Compared with traditional copper
smelting methods, the smoke amount of copper smelting in electric
furnace is small and the smoke temperature is low, which is
conducive to environmental protection.
3. Flexibility: electric furnace copper smelting can handle a
variety of copper bearing charge, including refractory charge,
oxide ore, sulfide ore, copper-bearing tailings, copper mud, etc...
Product process description:
1. Raw material preparation: First, prepare the charge containing
copper, usually copper concentrate. These concentrates need to be
prepared before refining, such as drying, pelleting, etc., to
ensure that the moisture content of the furnace material is
moderate, to avoid accidents such as tipping in the smelting
process
2. Ingredients and flux adding: The prepared copper concentrate
is mixed with appropriate amount of flux, the function of flux is
to promote the chemical reaction of the charge in the melting
process and the separation of impurities
3. Electric furnace heating and melting: the prepared charge is
added to the mineral thermal electric furnace, electric arc and
resistance heat are generated through the electrode, so that the
charge is melted under the action of electric heating. In the
molten pool, the charge will complete various chemical reactions to
produce copper matte, slag and other products;
4. Impurity separation: In the melting process, by controlling the
temperature and adding chemicals, various impurities (such as
arsenic, iron, sulfur, etc.) in the copper pool float on the
surface of the liquid copper pool, and discharge it in an
appropriate way to purify the copper liquid;
5. Cooling and casting: after impurity separation, the obtained
crude copper liquid or copper sulfur is cooled, and then cast
into the required copper ingot or copper billet.
