recovery iron slag

The recovery behavior of pig iron from copper smelting slag increases with increasing smelting temperature and duration. The recovery rate of pig iron varied greatly depending on the reaction temperature. Keywords: copper slag, reduction, pig iron, fayalite, recovery 1.

Abstract Copper slag is produced in large amounts in seven copper smelter plants in Chile, and it is estimated that around four million tons of slag are disposed every year, and another 40–45 million tons are historically cumulated. Copper slag contains iron in the range of 42–45%, which can be recovered and recycled along with the contained copper to obtain an iron–copper alloy and a ...

Recovery of iron from the slag was about 75 weight %. Power consumption was found to be 40 kWh. The main advantages of the present invention are: 1. The recovery of iron from the copper slag which was otherwise considered as a waste. 2. The produced alloy has the potential to be used as grinding media applications. 3.

Recovery of Iron from Copper Flash Smelting Slags Figure 3 shows the rapid decreasing of copper content in the slag during the first 15 min-utes with the graphite rod introduced into the melt, while the iron concentration is main-tained almost constant over same period of time, suggesting that a …

The alloy slag contains higher amount of iron and its physical characteristics are similar to air-cooled iron slag. alloy slag crushing plant - lesjoyeuxluronslauterbourg.fr. To improve total ferrochrome recovery while maintaining a high-quality product, alloy recovery plants are utilised to recover the ferrochrome from the slag produced during ...

Feb 03, 2018· Under the optimal conditions, 93.67% iron from the raw ore was recovered in the form of iron nugget with 95.44% iron grade. After a water leaching process, 85.61% of the vanadium from the roasting slag was leached, confirming the sodium oxidation of most of the vanadium oxides to water-soluble sodium vanadate during the roasting process.

On this basis, a review of a number of methods for recovery of metals from the slags was made. It can be seen that a large amount of slags is produced each year. They usually contain a quantity of valuable metals except for blast furnace slag and they are actually a secondary resource of metals.

P.K. Jena. A study of the recovery of copper, nickel and cobalt from copper converter and smelter slags by leaching with ferric chloride is reported. The converter slag from Ghatsila, India ...

Iron recovery from a lead slag in Henan province was carried out with the technique of coal-based direct reduction followed by magnetic separation. Scanning electron microscopy (SEM) was …

Abstract: The recovery of iron from iron sinking slag and lead smelter slag was investigated by desulfurization-reduction bath smelting. The effects of lead smelter slag (LSS) to iron sinking slag (ISS) mass ratio and temperature were investigated in desulfurization experiments.

Jun 04, 2020· 10%· Recovery of iron from copper slag can be realized while the secondary resources are rationally utilized. Experimental. Materials Copper slag. The copper slag used in the experiments is by-product generated during refining of copper in a non-ferrous metals group located in the east China. It is gray after drying, and 95 wt.% of the copper slag ...

Jun 17, 2021· Jun 17, 2021· Iron slag recovery grinding mill. Grinding is to break the large iron ore slag and associated appendages into small pieces or powders for the use of sorting waste. There are two grinding methods: mechanical grinding and material grinding. Mechanical milling is one of the most commonly used milling methods. The main grinding machines include HC ...

This will produce a discard slag containing approximately 10% total iron. The amount of recovery actually sought will of course depend upon economic considerations. Generally, the recovery range will be 60-80% of the total iron present in the slag to produce a discard slag containing 8-20% iron.

Jun 04, 2020· Recovery of iron from copper slag can be realized while the secondary resources are rationally utilized. Experimental. Materials Copper slag. The copper slag used in the experiments is by-product generated during refining of copper in a non-ferrous metals group located in the east China. It is gray after drying, and 95 wt.% of the copper slag ...

The terms blast furnace slag (BFS) and granulated blast furnace slag, as well as LD slag and electric furnace slag are used for finer distinctions. With high-quality iron ore grades with an iron content of 64 to 67 %, a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron.
