The utilization of low-grade laterite ores has become necessary due to the intensive mining of high-grade nickel sulphide ores for a long time. In this study, metallic reduction roasting followed by magnetic separation to produce ferronickel alloy and abandon gangue minerals provides an effectively treatment for laterite ores. The experimental results indicate that ferronickel alloy containing more than 7.5% Ni with its recovery of 95% and more than 70% Fe with its recovery of 90% was produced successfully from the low-grade laterite ore. In the metallic reduction roasting process, the thermodynamic analysis displayed that the higher temperature promotes the conversion percentage of the oxidic nickel and iron to metallic nickel and iron. The ferronickel particle morphology with a liquid-solid growth and aggregation mechanism in the reduced laterite ore were investigated by SEM/EDS. XRD analysis revealed that the nickel laterite ore was transformed from hortonolite (MgO x · FeO 2- x · SiO 2 ) to forsterite (MgO x · CaO y · SiO 2 ) during the metallic reduction process.

Steel slag is a large discharge of industrial waste slag. Chinese effective utilization rate of steel slag is only 20%, causing great harm to the environment and economy. Based on the introduction of the element, composition and characteristics of steel slag, this paper expounds the application of steel slag in sintering and blast furnace production, steel slag cement, road engineering, agricultural fertilizer and environmental protection at home and abroad.

Vacuum induction melting technology was used to prepare Mg-8Li alloy. Magnesium and lithium alloy chips were reacted with aqueous solution. The hydrogen production rate and hydrogen production rate of the alloy were tested and characterized by drainage method. The effect of NH4Cl solution with different concentration and temperature on hydrogen production rate and reaction degree of Mg-8Li based alloy was investigated. The results showed that with the increase of NH4Cl concentration and hydrogen production, NH4⁺, Cl⁻, and H⁺ could promote the hydrolysis reaction. Hydrogen production volume at 25 °C and 45 °C range increases with temperature decrease, high hydrogen content increases with the temperature when it is higher than 65 °C.
