Copper Smelting Slag Recycling Processing Line
 

Copper smelting slag is kind of solid slag from copper smelting processing, and there is a certain content of copper granules in this slag. The Cu content changes according to the smelting technology difference. Here Forui shares some efficient way to recover the copper granules.

The copper smelting slag recycling line is the recovery line about copper granules from copper smelting slag, so crushing, vibrating screening, washing separation and dewatering shall be involved in the whole copper recovery flow sheet which is similar to a line of ore beneficiation. The specific copper recovering flow chart can be designed according to copper smelting slag.

Copper Smelter slag

Generally, the copper granules are coarse inlays with its uneven round shape in the smelting slag. And liberation of the copper granules from the smelting slag is a premise to separate the copper granules. Here crushing equipment will be needed to crush the slag and liberate the copper granules. The crushed material is not so even, and some are liberated while some are not. So screening plant will be needed to get the liberated material and non-liberated material. The liberated will go for further separation while the non-liberated will go back to the crusher for second crushing. The copper separation plant is very important, and there are two kinds of machines to choose, one is copper jigging separator and the other is shaking table. Copper jig machine is used to recover copper granules of uneven size both fine and coarse while shaking table is adopted to get fine copper granules. The tailings after the processing line can be dewatered for piling or conveying. So dewatering plant is designed at the end of the whole processing line to meet the dewatering need of concentrate and tailings, and the dewatering machine used most commonly is linear dewatering screen.

Copper metal Recovered in the smelter slag.

The copper smelting technology is different, so the copper granules distribution is different, and different separation machine shall be adopted to get the copper granules from copper smelting slag. The following picture is about the copper granules recovery from smelting slag in Liaoning, China. The separation machine is jigger to get copper concentrate.

Copper metal  After Pickling

From the picture of the raw smelting slag, there are coarse copper and also fine copper granules, and by jigging, the copper granules can be recycled efficiently and the recovery is high, so the copper recycling flow sheet can be: crushing-screening-jigging or shaking table separation-dewatering. 

Forui is professional in ore beneficiation and smelting slag recovering, and rich experience about recycling of silica-manganese smelting slag, chromite smelting slag, stainless steel slag, carbide slag, copper smelting slag can be shared with you. Forui can supply test if samples of 15-20kgs can be available. Flow chart can be designed according to the test as well. You are highly welcome to Forui.
