The Sudan 7000t/d gold mineral processing plant was an EPC+M+O project. The ore of this project contained 2.97g/t of gold, most of which were earthy minerals with particle size below 2mm. A small part of the ore was blocky minerals, and the maximum particle size was 70mm

The Mongolia 1,000t/d gold mineral processing plant was an EPC+M+O project. Xinhai worked to achieve high recovery of gold and other valuable minerals by cutting costs and maximizing benefits and attach great importance to workers’ safety, environmental protection and energy conservation

copper: why this heavy metal is good for you

Copper is a mineral found throughout your body. It’s a nutrient that your body must have to function properly. You only need trace amounts of this heavy metal. Lead, mercury, and arsenic are examples of heavy metals that aren’t good for you. But getting copper in trace amounts is essential. Getting too much of it or not enough of it can cause health problems.

Copper has attracted interest as a therapeutic agent. According to a study in Medicinal Research ReviewsTrusted Source, copper is a possible treatment for a number of conditions, including degenerative neurological disorders, such as:

The results of research on copper’s effect on cancer are mixed. One study published in the Journal of Mammary Gland Biology NeoplasiaTrusted Source suggests that copper may cause cancer. But a growing body of research indicates that copper compounds can work against certain cancer cells. An Italian study published in the journal Dalton Transactionsshows copper to be nearly as effective as cisplatin, which is a commonly used chemotherapy drug. The researchers found copper to be three times more effective than cisplatin in treating adenocarcinoma of the colon, which is one type of cancer

Magnetic therapy bracelets have long been promoted as wearable treatment for arthritic pain. British scientists decided to put copper bracelets to the test in a placebo-controlled trial. The results, published in the journal PLoS ONETrusted Source, showed that the bracelets offered little or no therapeutic benefit. Furthermore, several study participants experienced skin irritation from the bracelets

copper: why this heavy metal is good for you

Because your body needs so little copper, you might think you can get enough just by eating a balanced diet. However, some researchers are challenging this belief. An article published in the Journal of Trace Elements in Medicine and Biology notes that copper has been decreasing in Western diets since the 1930s. These researchers estimate that one-quarter of adults in the United States don’t get their daily requirement of copper.

According to the University of Pennsylvania School of Nursing, people with sufficient levels of iron can still be anemic. If blood test results show that you’re not getting enough copper, your doctor may recommend that you take supplements. Copper supplements are available as pills and capsules. You can also get copper intravenously, or through your veins. You shouldn’t take copper supplements and zinc supplements at the same time. You should take these supplements at least two hours apart

froth flotation process

The Froth Flotation Process is about taking advantage of the natural hydrophobicity of liberated (well ground) minerals/metals and making/playing on making them hydrophobic (water-repel) individually to carefully separate them from one another and the slurry they are in. For this purpose we use chemicals/reagents:

The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests. It was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the Cattermole process. This was the beginning. When it became clear that froth flotation could save the ‘extremely fine free mineral’ in the slime, with a higher recovery than even gravity concentration could make under the most favorable conditions, such as slime-free pulp, froth flotation forged ahead to revolutionize the nonferrous mining industry. The principles of froth flotation are a complex combination of the laws of surface chemistry, colloidal chemistry, crystallography, and physics, which even after 50 years are not clearly understood. Its results are obtained by specific chemical reagents and the control of chemical conditions. It not only concentrates given minerals but also separates minerals which previously were inseparable by gravity concentration

This new process, flotation, whose basic principles were not understood in the early days, was given to metallurgists and mill men to operate. Their previous experience gave them little guidance for overcoming the serious difficulties which they encountered. Few of them knew organic chemistry. Those in charge of flotation rarely had flotation laboratories. Flotation research was done by ‘cut and try’ and empirical methods. The mining industry had no well equipped research laboratories manned by scientific teams

Froth flotation, as pointed out previously, was a part of the evolution of milling during the first quarter of the 20th century—a period during which the progress of milling was greater than in all of its previous history. It marks the passing of the stamp battery, after 400 years service to the mining industry, and the beginning of grinding with rod mills, ball mills, and tube mills without which neither the cyanide process nor the froth flotation process would have reached full realization. More than all of these, it was the time when custom and tradition were replaced by technical knowledge and technical control

froth flotation process

This volume, then, is dedicated to those men who, with limited means, made froth flotation what it is today. It is designed to record the impact of this great ore treatment development on the mining industry both present and future

“The single most important method used for the recovery and upgrading of sulfide ores”, that’s how G. J. Jameson described the froth flotation process in 1992. And it’s true: this process, used in several processing industries, is able to selectively separate hydrophobic from hydrophilic materials, by taking advantage of the different categories of hydrophobicity that are increased by using surfactants and wetting agents during the process also applied to wastewater treatment or paper recycling
