The iron valance state and the initial solution pH were the two variables with the largest effect on iron precipitation Increasing the initial pH from 25 to 4 increased the percentage iron precipitation from zero to 111% and from 687–791% to 100% for ferrous and ferric ion solutions, respectivelyA process for the treatment of a solution containing at least ferric ions, and one or more metal values, said process including the step of maintaining a controlled concentration of ferric ions in solution for a sufficient residence time to control iron hydroxide or oxide crystal growth, and precipitating the iron as a relatively crystalline iron hydroxide or oxide while minimising the loss of WOA1 Iron precipitation Google Patents An effective iron ore tailing Fentonlike process was developed to remove AO7 from aqueous solution AO7 was completely degraded within 60 min when the converter slag iron tailing, containing 737% iron oxide and a small quantity of Cu and other metal elements, was used as the catalystEfficient degradation of Acid Orange 7 in aqueous
Precipitation of Rare Earth Slag and the Crystallization
Isothermal reduction experiments at 1400 °C, which used carbonbearing pellets mainly made from Bayan Obo complex iron ore and pulverized coal, could effectively separate rare earth (RE) slag and iron Different instruments were used to study the precipitation of RE slag and the growth behavior of the RE phase in RE slag during the process of cooling from 1400 °C Initially, sponge iron produced at the Ray Mines Division for use in a LPF leachprecipitationflotation process was used in exploratory tests to develop a suitable apparatus to take advantage of the rapid precipitation rate and efficient iron utilization Copper Precipitation Cementation using Scrap Iron Egyptian wet process phosphoric acid (WPPA) produced from ElSebaiya phosphate area by Abu Zaabal Company contains about 26% iron The high concentration of iron is the main reason for many problems and inhibits using the acid in various industrial and fertilizers applications In this study, two types of additives were studied to decrease the iron content from WPPA using oxalic acid and Precipitation of iron from wet process phosphoric acid
