Gold ores can be divided into free milling and refractory types. The former are easy to treat by cyanidation process and they give good gold recoveries without pretreatment, over 90%, whereas the latter are difficult to treat and give gold recoveries less than 90% and in some cases less than 50% in cyanidation process.

The majority of resource at Akoko North comprises shallow, free-milling oxide ore with high metallurgical recoveries, Goldcrest said. Goldcrest Resources to Buy Akoko Gold Project in Ghana Major shear zones hosting large veins trend north-easterly and as the Lupa Goldfields are known to have coarse gold, the ore in the area is free-milling with …
Aug 06, 2015· We had a customer send us some very high grade gold quartz ore which we recovered 1.310 troy ounces from only 300 lbs! We ran the quartz through our 1/2-1 ton per hour complete turnkey processor comprised of out jaw crusher, hammer mill, and shaker table modules.
Conventional Uranium Mills. Conventional milling is one of the two primary recovery methods that are currently used to extract uranium from mined ore. A conventional uranium mill is a chemical plant that extracts uranium using the following process:
One free milling gold ore received for testing the application of the Mineral Jig in the Ball Mill Classifier circuit gave the following results: Head Ore, 0.65 oz. Gold per ton (Assayed) 0.643 oz. Gold per ton (Calculated) Amalgam from Amalgamation of Jig Concentrate: 0.471 oz. Gold from one ton head ore, or 73.3% of Gold from the original heads.
At the outset, when the ore to be milled was mined at or near the surface, 80% of the values were recoverable by amalgamation, and a 90% recovery could be made by a simple amalgamation and table concentration process.

A standard ball mill may grind your ore to 75 microns. Fine grinding is one process available to liberate refractory gold. Gravity Recoverable Gold (GRG) refers to how much gold you can recover based on how fine you are grinding/milling your ore. The GRG (Gravity Recovery Gold) testing is available at Met-Solve Labs.
