The average ore grade in the metasediments and metavol-canics is about 20 g/t although up to 50 g/t is reported in some places (Oberthür et al., 1994). The bulk of the ore of the mine consists of the gold-sulfide disseminated ore in the metasediments and metavolcanics (Kesse, 1985). 4. Sampling and Methods Polished sections were prepared from ...
Review of gold extraction from ores
REFRACTORY GOLD ORES A mineralogical examination of the ore normally suggests reasons for the refractoriness of the ore. Vaughan [76] identified specific mineralogical techniques, which can be used for specifying ore type and for location of the gold in the ore. These techniques are listed in Table 2.

Using Kerosene as an Auxiliary Collector to Recover Gold …
Carbon–arsenic-bearing gold ore is a typical complex refractory gold resource. Traditionally, xanthate was often used as a flotation agent to separate gold minerals. But, in this paper, in order to reduce the cost of the agent, kerosene was used as an auxiliary collector, and the gold grade and recovery rate were increased by about 10 g/t and 5.5%, respectively. …
