Enhancement of Iron Recovery from

28/07/2016  Steelmaking slags are usually processed for iron recovery by dry magnetic separation. The recovered iron-rich products are recycled back into the ironmaking and steelmaking processes to replace high-cost steel scrap and iron ores. However, current slag processing is far away from optimum conditions, especially for slag fines with small particle sizes, resulting in generation of nonrecyclable ...

RECOVERY OF IRON FROM COPPER FLASH SMELTING SLAGS

CHAPTER 01 Metal Recovery INTRODUCTION The flash smelting process has been used in copper industry for a number of years and has replaced some conventional copper smelting processes in Chile. The high copper content in the slag in this process, require

Recovery of high grade iron compounds from LD slag by ...

10/01/2014  According to them, the higher recovery yield of the iron from steel slag is obtained on the slag slowly cooled. This can be explained by increased amount and size of the crystalline phases, and decreased glass matrix during the slow cooling of the liquid slag. In this work, the LIMS and HIMS were performed on LD slag to separate iron rich compounds from iron free minerals. 2.2.3. Low and High ...

Iron Recovery From Slag Processing

Waste copper slag is a refractory material with high iron content, but it is difficult to recovery iron minerals from the slag because the iron mainly occurs in fayalite. A new technology of coal-based direct reduction-magnetic separation process was developed to recover iron from the slag assaying 39.85% Fe total and 0.33% Cu.

The process was optimised for iron-rich residue (matte), but also a proof-of-principle is given for lead recovery from another lead-containing residue (slag). The main advantages of this solvometallurgical process are the low power consumption (room-temperature process), the low consumption of chemicals (only sulphuric acid is consumed), full recycling of the acetic acid and the limitation of ...

Iron Recovery from Discarded Copper Slag in a RHF Direct ...

Studies on the direct reduction of carbon-bearing pellets made from discarded copper slag have been conducted in this paper. They include the influences of reduction coal content, limestone content, industrial sodium carbonate content, reduction temperature, reduction time and layers of carbon-bearing pellets on reduction effect. Finally, the optimum conditions have been obtained.

20/11/2016  Iron recovery exhibited a maximum value at Al/FeO = 0.53. To determine the iron recovery, a novel triangular material balance diagram, which represents the balance among the reduced iron ingot, the reduced iron droplets dispersed in the slag phase, and the residual (unreduced) iron, was proposed. Solid compounds, such as spinel and olivine, were precipitated in the slag during the ASR process ...
