Silica was extracted from nickel laterite ore by hydrothermal process with sodium hydroxide as reaction assistant. The effects of reaction temperature, reaction time, and NaOH-to-ore mole ratio on the extraction rate of silica were investigated by a single-factor experiment. The optimal reaction conditions for the preparation of silica were obtained as follows: reaction …

iron and steel industry is in the form of pellets. Other forms of processed ore include sinter and briquettes. The average iron content of pellets is 63%. 2.2 Mining Methods. Iron ore mining methods vary by the type of ore being mined. Currently, there are four main types of iron ore deposits, depending on the mineralogy and geology of

For silica sand containing a large amount of clay minerals, washing and classifying should be carried out before beneficiation to remove clay substances, improve the beneficiation efficiency, and reduce the grade of impurity minerals such as iron and aluminum. In addition, the finer the grain size of the quartz sand, the higher the g…
