Subscription journals recoup the costs of publication by charging a fee to access the content. As Gold Open Access content is freely available the costs are defrayed through article-processing charges (APCs). APCs are levied after article acceptance prior to publication and vary depending on the respective publisher, journal and discipline.
The Miller process is rapid and simple, but it produces gold of only about 99.5 percent purity. The Wohlwill process increases purity to about 99.99 percent by electrolysis. In this process, a casting of impure gold is lowered into an electrolyte solution of hydrochloric acid and gold chloride.

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well ...
Start by reducing the size of gold to smaller. Melt gold, pour gold while melting through a 2 mm sieve into the water. Reducing the size of gold to smaller Will help in the process of aqua regia to make gold into the solution more quickly. aqua regia is composed of 2 chemical substances, 1 nitric acid, 3 hydrochloric acid mixed together.

Of all the methods of extracting gold & 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 unit operations were utilized to evaluate the principal flowsheets. This page offers a comparative review of gold recovery ...
