  • Fine Gold and Mesh Sizes – Part One – Gold and Gem

    don’t “lecture me” about how fine your gold is. Instead let’s take a look at gold sizes and terms. Fine gold is often called “Flour Gold” and is very fine gold that looks like “baking flour”. For most it’s in the 100 – 200 mesh range. Most “fine gold” that prospectors deal with is in the 50 – 100 mesh range.

  • Vat Leaching of Finely Crushed Gold Ore

    Vat leaching is carried out in vats ranging in capacity from 30 to 1200 tons. Sand for leaching is separated from slime in cones, V boxes, classifiers, and in collecting vats filled by distributors—the overflow in each case being slime or finer portion of the ore. As a rule, leaching is a simple process, involving a vat of well-mixed neutralized sand, ample contact with strong and weak ...

  • » Double-screen Classification System in Dredging

    Classification is the Key to Fine Gold Recovery. It is well-established that if you want to effectively recover finer particles of gold, you must first separate them from the larger-sized materials which are being washed through your recovery system by a higher-velocity flow of water. The small-sized material can then be directed to a milder-flow of water over a shorter set of riffles.
