NOTES ON FLOTATION TEST WORK AT ANYOX ON GRANBY ORES
The Granby ores may be divided into three groups or classes. The No. 1 ore is a heavy pyrite, chalcopyrite, pyrrhotite, sulphide carrying some free silica, and calcite. No. 2 ore carries the same general group of sulphides as does No. 1, but in a lesser amount.
