The flotation plant design was based on extensive benchscale testwork including locked cycle tests on drill core and many months of operation of a 30 tonne per hour “pilot plant” using the old Cleveland Tin Mine process plant modified for the duty. The Cadia concentrator was designed on an extensive benchscale variability testwork
A number of flotation plant have been simulated that incorporated a variety of circuit configurations encompassing rougher and cleaner scavenging banks two or three stages of cleaning regrinding of rougher concentrate open or closed circuit cleaning and pulling final concentrate from the first cell s of a roughing or first stage cleaning bank.
Zinc Flotation. The purpose of the zinc flotation circuit will be to recover a zinc concentrate. Tailings from the bulk flotation circuit reports to a condition tank prior to the zinc circuit where copper sulphate lime collector and frother are added. The conditioned slurry will be then pumped to the zinc rougher cells. The zinc flotation
Mining Methods. Truck and Shovel / Loader. Summary: The Scotia Mine deposit covers a total strike length of approximately 4 kilometres with some surface constraints in between and a vertical distance of approximately 120 metres. All mining is from open-pit operations with an expected mine life of approximately 14 years.
MINING METHOD. Red Dog is an open-pit mine using conventional truck-and-shovel methods with special provisions for operating in the Arctic climate. High grades low stripping ratio 0.8:1 and short haul distances result in the low mining rate of 10000t/d. Bench heights are 7.6m and pit slopes vary depending on wall material.

BMM is lo ed at Aggeneys a mining town in the province. Ownership: Vedanta holds 69.6%. Exxaro Resources a leading South African BEE company owns 24.4% and ESOP holds 6%. Comprises: Gamsberg will exploit one of the largest known undeveloped zinc orebodies in the world and comprises an open pit mine and a dedi ed processing plant. Production:
The Buenavista copper mine is lo ed in the outskirts of Cananea in Sonora Mexico. The Buenavista mine produced 965 million pounds of copper in 2019. The company is also implementing a zinc project at Buenavista with an estimated investment of £315m $413m . Scheduled for commissioning in the second half of 2022 the Buenavista zinc project
