2021-2-18Mining chemicals represent a niche area of supply but at the same time their use is almost universal across the industry. In this month's im-mining Spotlight Feature Article, from the June issue of International Mining magazine, Editor Paul Moore looks at the players, challenges, and future horizons for the sector.

The studied factors are, grain size, uranium distribution, agitation time, and sulphuric acid concentration. Percolation (column) leaching experiment: Recommended columns materials are PVC pipe with 12-inch inside diameter. The bottom of the column equipped with a PVC base plate containing a piece of screen to prevent loss of solid sample from
2021-2-6Model for predictive analysis of the quantity of heat absorbed by oxalic acid solution during leaching of iron oxide ore has been derived. It was observed that the validity of the model is rooted in the expression (lnQ)/N = √T where both sides of the relationship are correspondingly almost equal. The model was found to depend on the value of the final solution temperature
The optimum leaching pro- cess removed iron from originally 1.44% to reach a level of 0.243% (82% removal of iron) with the SiO2 content increases from 95.50 up to 97.77%. The obtained beneficiated quartz sand matches the required Fe level for glass insulating fibers industry, which is less than 0.3%.
Sulphuric acid leaching of zinc and copper from Nigerian allurgical process. However, sulphide ores do not allow the recovery of metal by direct chemical leaching (Hiskey and Wadsworth, 1975; Dutrizac, 1989), due to their low solubility in most leaching reagents.
2014-8-12Silica sand processing is of varying degrees of complexity, and depends on the nature of the raw material and the end use of the sand. It typically requires a high capital investment in plant. Processing is aimed at improving both the physical and chemical properties of the sand to meet user specifications. Hot sulphuric acid leaching is

A process for leaching silica sand to reduce the iron content thereof comprises the steps of drying- preheating the sand; vigorously mixing the preheated sand in a suitable intensive mixer, e.g. a rotating pan mixer, with sufficient sulphuric acid (e.g. 7.5 kg H2SO4/tonne sand) to keep the surface of each grain of sand coated with a thin film of sulphuric acid during mixing;
2012-8-23sand during 2002–2003. In 2003 GZB started extracting zirconium from zircon sand by means of NaOH cracking on a commercial scale. Experience has shown that temperature profile and atmospheric control inside the furnace is crucial for the beneficiation of zircon sand. Silica carryover to zirconium chemicals could result if a high temperature
The acid leaching and calcification tests were conducted based on the treated silica sand medium intensity magnetic separator non-magnetic product. A variety of concentrations of sulphuric and hydrochloric acids were used for the same. Samples were heated to 90 degrees C and acid leached for 6 hours
2010-12-1Leaching experiments were conducted for investigating the effect of leaching time on the condition of 0.44 mol/L sulfuric acid, 140 C temperature. Results are plotted in Fig. 6, which shows that leaching time has no remarkable effects on the zinc extraction percentage but evidently affects the dissolution of iron and silica. It is seen that
Of great interest to this study is the work of Das et al. (1978). Das et al. did some leaching work on ferromanganese slags using hydrochloric acid and sulphuric acid at different temperatures, ranging from room temperature to 99C. Silica gel polymerisation was observed as being a major problem during filtration.
