The Al2O3 concentration in the slag is considered to be a factor which degrades the slag fluidity and increases the liquidus temperature. The effects of high Al2O3 in the slag are as follows.Effect of Ore Pulp Density and pH Value on Silica in Iron,08/02/2020· Iron ore flotation is an efficient method to remove impurities from iron ore. Some amount of silicon dioxide is found in the ore even after separation from the magnetic and hydraulic mechanism. The most widely used method of flotation is the reverse cationic flotation route. The low-grade iron ores contain high grades of silica and alumina. They are detrimental for the production of steel as,The Latest Iron Ore Price Slump: Causes And Effects,14/03/2014· The price of iron ore averaged $126 in 2013 and Rio stated in February this year that a 10% drop in that figure would erode its underlying earnings by $1.2 billion.
