Eriez Permanent Magnetic Flocculators aid in the separation of minute magnetic particles from liquids and slurries. They are used widely in the iron and coal mining industries to speed settling of fine magnetic particles in ore slurries and heavy media slurries. They are also finding new use in steel and other industries for agglomerating fine magnetic contaminants in quench water, cooling oils etc.

In China, iron ore with hematite grain size of less than 0.045mm or magnetite grain size of less than 0.03mm is commonly referred to as fine-grained iron ore [18]. Yuanjiacun Iron deposit and Qidong Iron deposit in Shanxi and Hunan Province, respectively, are the most typical fine grain iron deposits in China. The Taiyuan Iron and Steel Group and scientific research units, who aimed at the Yuanjiacun iron ore recycle and conduct a large number of experimental studies. The original iron ore grade of 31.18%, −0.045mm particle size accounted for 93.81% of the total ore, they got concentrate iron grade 66.95%, and recovery rate of 72.62%. With this process, the Yuanjiacun iron deposit built a mineral processing plant with annual capacity of 22 million tons by the end of 2012 [19]. Changsha Institute of Mining and Metallurgy proposed a selective flocculation desliming-anti-flotation technology and developed a SA-2 flocculant (for the purpose of fine grain size, complex nature of igneous iron ore in Qidong iron deposit) [20]. At present, the Qidong iron deposit uses this technology to build a beneficiation plant with an annual treatment capacity of 2.8 million tons. Under the conditions of a raw ore grade of 28.36% and a grinding fineness of −0.038mm (98%), the concentrate iron grade 62.5%, the recovery of 68% have been achieved [18, 19, 20]. There are many examples like this. Stage grinding—stage magnetic separation likely is the best process for processing fine-grained magnetite [21, 22]; for fine-grained magnetite-hematite mixed iron ore, weak magnetic—strong magnetic—resurfacing—reverse flotation process can obtain the high recovery rate; that sorting fine particles hematite process mainly has strong magnetic—desliming—reverse flotation [23, 24], selective flocculation—reverse flotation [25] and strong magnetic—centrifugal beneficiation [26].

Modern metallurgists, much the same as their ancient counterparts, have considered the problem and devised a number of solutions, including crushing with toothed rolls which shreds any coarse copper lumps rather than trying to break by impact; removal of the coarse lumps by gravity or ore sorting ahead of grinding; removal of fine native copper in the grinding circuits ahead of flotation by means of equipment such as spirals and shaking tables which use the specific gravity of copper to separate it from the rest of the waste and valuable minerals in the ore.

The cross-belt separator (Figure 13.17) and disc separators, once widely used in the mineral sands industry, are now considered obsolete. They are being replaced with rare earth roll magnetic separators and rare earth drum magnetic separators (Arvidson, 2001).

The most distinguishing property of Magnetic Roll Separators as Magnetic Separator is, the magnets are an alloy of rare earth elements produced domestically and more powerful. Magnetic Separator System has a number of standard sizes in which the high gradient separators are produced, and all of these sizes only require a low installation height. It is also possible to make a system in accordance with customer specifications. Depending on the requirements made and the application for Magnetic Separator, a choice can be made for a single stage system or for multiple magnet rollers under one another. This results in an even higher degree of iron separation.

Due to its special properties, ground calcium carbonate powder can be used in many areas. For example, the calcium carbonate powder are usually applied in paper, construction, paint, plastic, glass and other industries as filler, adhesives and so on. For instance, in paper industry, calcium carbonate is often used as an inexpensive filler to brighten opaque paper, due to its high brightness and light scattering characteristics. Of course, different usages have different requirement for the finished calcium carbonate powder, while high quality calcium carbonate with great whiteness have greater economic value. And there are several factors that can affect the quality, fineness, whiteness and surface of the calcium carbonate powder. One is the quality and properties of raw materials to be processed. Another important factor is the grinding system, wet or dry grinding mill, which can have an impact on the whiteness and fineness of the end product. In line with your needs, Daswell will provide tailored turnkey solutions for your calcium carbonate manufacturing process with consideration of costs. We assure that the customized ground calcium carbonate plant will of great economic value for your corporate with consideration of environment as well as costs.

In the United States, strict laws govern gold purity labeling. To be labeled as a specific karat, a solid item must be within three parts per thousand of the karat marking. Items containing solder must be within seven parts per thousand. Pieces that fail to meet these criteria must receive a lower karat designation.

One of the biggest copper mines in Mexico is Grupo Mexico’s (BMV:GMEXICOB) Buenavista del Cobre operation in Sonora, also referred to as Cananea. It has been in operation since 1899 and has an estimated copper reserve of almost 27 million MT.

In classification, hydrocyclone and vibrating screen can enhance the classifying effects.

Chemical methods play an essential role in mineral processing, especially in mine operations for low-grade ores.

Thousands of years ago in Mexico, native genius -- or historical serendipity -- unlocked the nutritional secrets of corn.
