Gold processing 101 - Mining Magazine

In most cases, gold processing with cyanide leaching, usually with carbon adsorption, is still the core technology and the critical thing is understanding the mineralogy in order to optimise flowsheet selection and cost drivers, and get the best out of the process. Metallurgy: the science of bashing, mashing and hashing! Metallurgical processing of metalliferous ores in general and gold

FLOWSHEET DEVELOPMENT FOR GOLD OREBODIES

There are several basic metallurgical flowsheets used to treat gold orebodies, with a great many permutations. The optimum flowsheet from an economic perspective is always that which achieves the greatest gold recovery at the lowest cost. Normally these two are mutually exclusive and some measure of compromise is required. The grade of gold in the orebody can be critical in establishing the ...

» The Basics of Successful Gold Mining-Part 1

Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the “pay-streak”. Pay-streaks always form along the gold path where the river’s flow slows down on a large scale during a major flood storm. One example is the tail end of an inside bend in a river. Centrifugal force ...

29/07/2013  First, bottle-roll tests of finely ground material are run to determine the ultimate recovery of gold, and for any preg-robbing characteristics of the ore. Next, leaching tests in columns are conducted for the same variables as for heap leaching. These include size of material, solution strength, agglomeration, and time of leach. For vat leaching, additional tests on flow rate, applicability ...
