P is unevenly distributed in steelmaking slag and generally concentrated in the 2CaO・SiO 2 phase as a 2CaO・SiO 2-3CaO・P 2 O 5 solid solution This evidence reveals the potential to separate P from steelmaking slag In this chapter various technologies for P separation and recovery from steelmaking slag are described

The kinetic behavior of Cr 2 O 3 reduction by iron melts containing carbon aluminum and silicon were investigated at various conditions in order to understand effective slag treatment for recovery of chromium from stainless slag It was found that the recovery rate of chromium was fairly slow but it was considerably accelerated by the addition of some fluxes such as Al 2 O 3 and SiO 2 to

All answers 4 please look at the article a process for the recovery of chromium and iron oxide in high carbon ferro chrome slag to obtain chromium and iron in the form of saleable metal by cn harman published via the thirteenth international ferroalloys congressefficient technologies in ferroalloy industry in this publish they attempt Details

slag recovery Valuable by-products Slag recycling Iron and steel slags are by-products of steel production These mineral raw materials mainly consist of lime silicate compounds and are classified as secondary raw materials and not as waste because more metal recovery "Without a doubt it's paid off

The present study was carried out to search for the possibility of the separate recovery of iron and phosphorus as gas from BOF slag by using graphite crucible or graphite powder with the presence of tin bath which is considered to enhance the activity of phosphorus in iron reduced from slag or not to absorb the phosphorus vapor readily

machines for recovery of iron from slag - gsssbanjarorg Lead smelting plant equipment for secondary Lead - machines for recovery of iron from slag The secondary production of Lead begins with the recovery of old scrap from Frequently this includes various forms of iron and slag enhancing materialsBlast furnace A blast furnace is a type of metallurgical furnace used for smelting to

Abstract The pig iron from steel manufacturing plants contains a high concentration of vanadium-bearing materials smelted with iron ore During the oxidation process of the molten pig iron with oxygen lances vanadium transfers to the slag In this

leach slag It was deduced that roasting prior to leaching was essential to ensure that the manganese was converted into a soluble form A manganese recovery of 82% was achieved in 2 hours at a temperature of 80˚C The oxidation of sucrose however increased the rate of leaching yielding an 86% recovery in 1 hour The pregnant leach solution

manganese loss into steelmaking slag is almost equivalent to that of manganese input into steelmaking process as ferro-manganese etc in both countries The results of material flow analysis suggest that a significant ripple effect can be expected if the recovery of manganese and phosphorus from iron- and steel-making slag becomes possible 3

Blast furnace slag is one kind of solid waste which is discharged from blast furnace And the temperature of molten slag ranges from 1450 to 1650 C In 2014 the output of blast furnace iron was more than 0 71 billion tons and there were about 0 21 billion tons molten slag discharged from iron making process
