Underground Gold Mineral Processingmethods

Of all the methods of extracting gold amp processing it from its ore, I used a few to evaluate two principal flowsheets in this case study. The flowsheets utilized operations that involved flotation,cyanidation and gravity concentration. Tests that mirror each of these unitoperations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery methods. We provide a large number of solutions for customers in more than 160 countries/regions around the world, and are committed to creating the most suitable solutions for customers.

The nominal primary grind size was 50um P80. Potassium Amyl Xanthate PAX was used as the sulphide mineral collector in the rougher circuit. The rougher circuit pH was maintained at natural through eight minutes of rougher flotation. For Tests 69 to 76 a gravity separation stage, including cyanidation of the gravity concentrate was included. Ultra-fine grinding of the flotation rougher concentrates was employed for selected tests to understand leach extractions of the concentrates.

The primary grind sizing, for Flowsheet 2, was a nominal 50um P80, two tests were conducted at a coarse crush size of 3.350mm P80 to assess heap leach amenability of the selected composites. Leaching tests were carried out at a sodium cyanide concentration of 1,000 ppm for 96 hours. The pH in the cyanidation circuit was maintained at 11.0.

Silver recoveries were higher using the flotation flowsheet withsubsequent cyanidation of the flotation concentrates. Recoveriesvaried between 59 and 81 percent of the silver in the feed, with anaverage of about 69 percent. Whole-of-ore cyanidation extractedbetween 29 and 47 percent, for an average of about 38 percent.

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their interest for gold is the most valuable tool for exploring new deposits.

Gold is a very widely disseminated throughout nature and may be found in any geological formation from the oldest rocks to the deposits that are still being formed, but in common with other metals, it is more likely to be found in the oldest rocks and in those places where the earth crust has undergone the most extensive changes such as elevations, folding, tilting, faults, fissuring and also volcanic action, with resulting changes in the composition and texture of the rocks.

In general, photogeology involves the interpretation of an areas geology from analysis of landforms, drainage and vegetation. Basically, there are four types of information, fracture and trace analysis, fracture identification, seep detection and channel change study. When a fracture is observed in cross section, it seems to be vertical or near vertical breaks in the bedrock. Gold particles can be deposited into fractures. Other important information is the called lithological mapping, which involves the interpretation of surface features so that can be obtained a more exact map.

Photographic surveys follow specified flight routes and take the photographs at regular spacing along the path. The overlap between adjoining photos in a sequence along the line is about 55-60 . The overlapped area is detected by the camera from two different views in two different photos. The two adjoining photos used together make what are called a stereo pair. The two photos can be placed side by side and observed with a stereoscope.

There are two ISR Au projects that have been running for many years, one of them on the outskirts of Ekaterinburg. The key factors in appraising a mineral deposit for in situ recovery ISR are the hydrogeological characteristics of the deposit, for if the ISR system cannot be confined it is not going to be viable environmentally. However for the right deposits it is a low cost solution to mining, while cutting out all the infrastructure and costs involved in conventional mining, which also itself has better known environmental issues.
