Keywords Flotation, Gold-bearing ores INTRODUCTION Gold is a relatively rare metal and the average content in the earth's crust is about 3ppb. The average gold grade of a low grade deposit is only some 3ppm and this low abundance makes the exploration, sampling, assaying and processing of gold bearing ores difficult.
