More recently the same research group described a method to extract cellulose nanofibers in high yield (93.1%) in the presence of the ionic liquids 1-butyl-3-methylimidazolium chloride (BMIMCl) and 1-ethyl-3-methylimidazolium acetate (EMIMOAc).57 These ionic liquids were chosen since they can easily dissolve cellulose. Ball milling was performed on cellulose pulp using a planetary instrument at 400 rpm for two hours. Purification was then undertaken by washing with distilled water. After the mechanical treatment was applied, the resulting fibrils maintained the same crystal structure as the starting material (cellulose I), while crystallinity and crystal size decreased depending on the employed ionic liquid. In particular, the CNFs extracted using EMIMOAc had a lower crystallinity, crystal size, thermal stability and yield. This was attributed to the higher ability of this medium to interact with the hydroxyl groups of cellulose compared to BMIMCl. Despite the cost of the ionic liquids, which are notoriously expensive, this method allowed the recovery of the medium, which could be re-used at least four times.
Other mineral processing and ore metallurgy technology would include the tailings re-separation technology and room temperature collector technology.  Due to the low grade of iron ore resources in China, an average of 1 ton of iron concentrates needs to be discharged to 2.5 tons of tailings. With the continuous increase of production capacity of mining enterprises, the discharge of iron tailings has rapidly increased and has become the largest industrial solid waste. Tailings discharge not only occupy a large amount of land, sometimes due to poor management, but also cause tailings dam break, resulting in casualties, environmental pollution, destruction of villages and towns and other serious consequences. The iron tailings usually contain a certain amount of metallic iron with a fine grain size, so the energy consumption of grinding is lower than that of raw ore. Anshan Iron and Steel Mining Company, Qidashan iron plant and Gongchangling beneficiation plant conducted flotation tailings re-separation pilot study. The results show that the pre-enrichment of iron minerals in the tailings can be achieved by the re-separation, grinding-magnetic separation and the iron concentrate with grade greater than 40% can be obtained. And then, via the process of grinding—weak magnetic—strong magnetic—reverse flotation process or 1 rough 1 fine 1 flotation column process sorting, reaching more than 64% of concentrate grade, the recovery rate more than 88% [38, 39, 40]. Meishan iron ore processing plant integrated tailings, strong magnetic separation tailings, phosphorus tailings on the basis of a comprehensive analysis of mineralogical characteristics of the re-separation were carried out: iron grade of 18% in the tailings can be concentrated to 56.5%. Experimental studies have shown that the nature of iron tailings in different regions vary greatly, hence iron tailings re-separation process is not the same . Most of the domestic iron ore beneficiation pl.
The consumption of flotation reagents is usually designated in lbs. per ton of ore treated. The most common way of determining the amount of reagent being used is to measure or weigh the amount being fed per. unit of time, say one minute. Knowing the amount of ore being treated per unit of time, the amount of reagent may then be converted into pounds per ton.
The iron ore beneficiation plant and the iron ore concentrate quality of our company has reached the international advanced level, but considering the Chinese iron ore features of deficiency, impurity and fineness, our company, as a leading iron ore processing line manufacturer, should not only promote the advanced iron ore beneficiation plant (including the flotation iron ore separation plant and magnetic iron ore separation process), but also try to optimize and simplify the processing technologies of magnetic separation, flotation separation and gravity separation.

Screens. Aggregate Screens are used for screening and processing various materials including mineral, sand, and gravel. We also supply and manufacture portable screening equipment, please contact with your requirements.
A mini mill contains both cutting and electric parts, so you want to exercise double caution while using it.
All conveyor models are of heavy duty construction to provide years of virtually maintenance-free use. High quality steel and non–magnetic stainless steel are used for the structure, slider plate and magnet assemblies.Conveyor housing construction is entirely liquid-tight (submerged units), and access panels are equipped with gaskets and seals.
Chris Wood has written Mini Mill User's Guide, a getting started booklet that should have been included with your mill. It describes all the controls and, more important, covers basic mini mill operations, such as squaring a vise, using a clamping kit, edge finding, and simple milling.
