Copper Smelting Process. In the autogenous system described by this report, sulfide concentrate and silica flux are blown into the furnace through a specially designed burner with oxygen and is flash smelted to about 50-percent copper matte. The matte flows down an inclined crucible, countercurrent to the slag flow, to the converting zone at

Sandblasting material copper ore slag Introduction Copper slag is mainly used for surface blast-cleaning. Abrasive blasting is used to clean and shape the surface of metal, stone, concrete and other materials. In this process, a stream of abrasive grains called grit are propelled toward the workpiece.

In the second treatment beginning with a water quench (fig. 4), the crushing operation is eliminated. Evaluations are based on the processing of 500 and 1,000 tons of slag per day, Process for Slow-Cooled Slag. Slag from the copper converter is skimmed into ladles, which are hoisted to a tilting machine.

The invention provides a two-step copper smelting process and equipment. The process consists of the steps of bottom blowing smelting and converting. The process equipment consists of a bottom blowing smelting furnace and two converting furnaces that are laid in the shape of a Chinese character ''''pin''''.

Thus, the two factors that most affect the loss of copper to slag in the smelting stage are: matte grade; mass of slag. This means that there is a practical limit on how high the matte grade can be if the loss of copper to slag is to be minimized. Therefore, further stages of processing (converting and fire refining) are required.

The process includes three operations similar to copper and nickel slag production: 1. roasting, 2. smelting, and 3. converting. Lead and zinc are often related as coproducts in both source and metallurgical treatments, and the various combinations of slags, which include lead, lead-zinc, and zinc, are similarly produced.

(0.7 % Cu and less) slag ensures optimal coalescence conditions for copper-bearing slag compo-nents. The slowly cooled slag is crushed and delivered to one of Kazzinc-owned concentrators for reprocessing. Re-extracted copper is sent back for pyro-metallurgical processing. Figure 5 gives a view inside the copper smelt building.

18.1.3 Old Scrap. The final category of copper scrap (paths (3), (3a) and (3′) in Fig. 18.1) is termed old, obsolete, post-consumer, or external arising scrap. It is obtained from products that have ended their useful life. Old scrap is a huge potential source of recyclable copper. It is also difficult to process.

Copper slag is an abrasive blasting grit made of granulated slag from metal smelting process ( also call iron silicate). Copper Slag abrasive is suitable for blast cleaning of steel and stone/concrete surfaces, removal of mill scale, rust, old paint, dirt etc. Suitable for SA-3, SA-21/2 and SA-2.

Copper slag is a by-product created during the copper smelting and refining process. As refineries draw metal out of copper ore, they produce a large volume of non-metallic dust, soot, and rock. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields.

Value-added Uses for Copper Smelting Slag . Proposed by Freeport -McMoRan Background Copper smelting is a high-temperature process that separates elemental copper from copper concentrates. Smelting leaves behind “slag” from the refining process. Once it leaves the smelter, the slag is poured onto the slag stockpile and is cooled in layers.
