Kinetics of Reduction of Iron Oxides and Ores by Carbon
ITIHEORETICAL considerations and experimental findings point out that reduction of iron oxides and I ores by carbon proceed via the gas' phase, whenever the latter is present. The overall reaction is a coupling of the following two component reactions, viz., Gasification of carbon C(S) CO2 (g) = 2C0 (g) and Reduction of iron oxide mFe.0y(S) -fCO (g) = nFezOw [S) CO2 (g) ' Recent kinetic studies...
متن کاملKinetics of chemical leaching of chalcocite from low-grade copper ore: size-distribution behavior
Kinetics of the chemical leaching of chalcocite from a low-grade copper ore in a ferric sulfate medium was investigated using the constrained least square optimization technique. The experiments were carried out for different particle sizes in both the reactor and column at constant Eh, pH, and temperature. The leaching rate increased with increase in the temperature. About 50% of the Cu recove...
متن کاملMineralogy and uranium leaching of ores from Triassic Peribaltic sandstones
The recovery of uranium and other valuable metals from Polish Peribaltic sandstones were examined. The solid-liquid extraction is the first stage of the technology of uranium production and it is crucial for the next stages of processing. In the laboratory experiments uranium was leached with efficiencies 71-100 % by acidic lixiviants. Satisfactory results were obtained for the alkaline leachin...
متن کاملContent and binding forms of heavy metals, aluminium and phosphorus in bog iron ores from Poland.
Bog iron ores are widespread in Polish wetland soils used as meadows or pastures. They are suspected to contain high concentrations of heavy metals, which are precipitated together with Fe along a redox gradient. Therefore, soils with bog iron ore might be important sources for a heavy metal transfer from meadow plants into the food chain. However, this transfer depends on the different binding...
متن کاملextraction and acetylation of purified trypsin from bovin pancreas and study of some its physico-chemical properties
آنزیم تریپسین در شرایط قلیایی ناپایدار می باشد .و فعالیت پروتئولیتیکی تریپسین منجربه خود هضمی آن در جایگاههای خاصی می گردد. بنابر این آنزیمی با ناپایداری بالا محسوب میگردد. در سالهای اخیر موفق شدند که با ایجاد تغیرات شیمیایی با اضافه کردن فلزات خاص ، کلسیم و یا عمل استیلاسیون منجر به افزایش پایداری آنزیم تریپسین گردند. مطالعات در حال حاضر نشان می دهد که تریپسین استیله شده فعالیت آنزیمی خود را ...
