Artisanal gold mining is the leading source of anthropogenic mercury emissions worldwide. This article explores cost-effective leaching methods for skilled miners to address mercury's environmental and health impacts in this sector. A sample from Colombia's La Maria deposit, containing 48.87 ppm gold, ground 80% below 0.13 mm, served as basis comparison. The standard whole ore amalgamation appr...

The enrichment of polymetallic sulfide ore is a complex task. Fine grinding carried out to reveal useful minerals, resulting in the formation microparticles. It difficult achieve floatation microparticles and fine minerals are lost with flotation tailings. problem microparticle can be solved by using air bubbles smaller than 50 µmin for process. Water-air microemulsion (WAME)of frothersolution ...

In the article, continuous growth in development of gold mining industry our country, consumption metals and other minerals justify search for new minerals, efficient technological schemes mining. processing types raw materials from difficult-to-enrich ores. Research is aimed not only at preparation deposits, determination enrichment gold-bearing ores, but also theoretical methods separating co...

gold preparations are one of the oldest disease modifying drugs in the treatment of rheumatoid arthritis. this are different reports about the effects and complications of these compoumis. these opposite reports may he due to the difference in genetic ami ethnic background of patients. this study was designed to evaluate our results in gold therapy ami compare them with those of western countri...

BACKGROUND Current measurement of the single longest dimension of a polyp is subjective and has variations among radiologists. Our purpose was to develop a computerized measurement of polyp volume in computed tomography colonography (CTC). METHODS We developed a 3D automated scheme for measuring polyp volume at CTC. Our scheme consisted of segmentation of colon wall to confine polyp segmentat...

The paper considers the most effective leaching solution for extracting gold; it was decided to test different reagents using IW method from spent uranium gold wells. And also Scientific experiments were carried out extract a productive in laboratory conditions, sorption process on various grades of activated carbon determine promising sample. In order saturate sorbent with solution, studies fo...
