Abstract
Temperature is an important factor affecting the sulfidation of laterite ore. The effect of temperature on the sulfidation of nickel in laterite ore was studied. The thermodynamic analysis shows that the sulfidation reactions of nickel oxide and iron oxide can be carried out at temperatures above 400 ºC and increasing temperature will promote the reactions. High sulfidation of nickel at high temperature will be achieved by regulating the partial pressure of sulfur and oxygen. In the atmosphere of high sulfur and low oxygen pressure, nickel and iron mainly exist in the form of sulfides. With the increase of temperature from 400 ℃ to 1200 ℃, the sulfidation degree of nickel in the ore increased initially and then decreased. At 1100 ºC, the sulfidation degree of nickel in the ore was the highest, reaching 84.43%. The size of nickel sulfide particles increased to about 10 μm.
