Ainsworth Gold Mill is a bespoke mill located on the shores of Lake Kootenay, British Columbia. 14 miles south of Kaslo and 30 miles north of Nelson. The mill processes silver, gold, lead and zinc. The Ainsworth mill was opened in 1949 and milled lead and zinc from the mine on site. The base metals were made into concentrates where then made ...

A "refractory" gold ore is an ore that has ultra-fine gold particles disseminated throughout its gold occluded minerals. These ores are naturally resistant to recovery by standard cyanidation and carbon adsorption processes. A refractory ore generally contains sulphide minerals, organic carbon, or both, generally leading to a …

Hard rock gold deposits can be further classified into three sub classes: free milling, sulfide associated and refractory. Free-Milling Gold. Gold ore is considered free-milling when over 90% of the gold can be recovered by a conventional gravity-cyanidation process with low reagent consumptions at a grind size of 80% passing 75 µm.

The newer Humphreys spirals are capable of recovering particles as small as 270 mesh (53 microns). In a test at CSMRI, a new Mark VII Reichert spiral recovered 91.3% of the free gold contained in the feed in a concentrate representing only 5.4% of the feed weight. See more

Previous work (Walsh, 1989, 1991, 1992) has shown that significant, free milling gold values exist in the Ryan Lode ore. Pilot scale gravity concentration tests have shown that free gold as coarse as 0.84 mm (20 mesh) occurs in the ore, closely associated with sulfide mineralization. ... The primary concentrator was a Reichert Mark VII spiral ...

Some other key drivers in flowsheet selection at the hashing stage are: Supergene weathering. This is common in tropical environments (e.g. West Africa) and typically oxidises gold-bearing sulphides down to 50-100m, transforming commonly refractory gold in sulphides to 'free-milling' gold, behaving in a similar fashion to gold …

The newer generation of 3.5m dia Reichert cones have a capacity in excess of 300 tph, and can dramatically reduce the complexity of plumbing of an equivalent spiral plant. Very large plants could consider (when the unit is metallurgically acceptable) 3.5m diameter roughers followed by 2m diameter cleaners, with spirals only for final cleaning.
