  • Development Of Underground Gravity Gold Processing Plants Ferret

    The concept of processing gold ores on the surface is a traditional paradigm. A process of preconcentration or . Milling costs in 1995 were about GB15 per tonne. Prior to 1995, a small gravity circuit with a 0.5 t per hour capacity was in operation based on a single 7.5 Knelson Concentrator. This unit was a batch process,

    In times of higher prices, mining lowgrade ore will become profitable as the higher price offsets the increased cost of extracting and milling greater volumes. When the price is lower or costs rise, it might only prove profitable to extract and process highergrade ores. Mine plans are regularly reassessed as market conditions
