Mining History :: Mineral Resources Authority of Papua

When Papua New Guinea gained independence in 1975, Panguna was the only major mine operating. As the price of gold rose in 1974 and again more spectacularly in 1979, there was increasing international recognition of the gold potential of Papua New Guinea. This led to a significant increase in applications for Exploration Licences.

Chromite deposits of Papua New Guinea a future potential

Abstract. The chromite deposits of Papua New Guinea occur in the New Guinea ophiolite belt that comprises the peridotite-gabbro-basalt complex. The two most important of these deposits, the Ramu and Hessen Bay chromites occur disseminated in dunites, harzburgites and pyroxenites and are uneconomic in their primary forms.

Flotation Reagent an overview ScienceDirect Topics

There are six gold mines in the Australasian region that treat refractory gold ores. The largest of these is the Porgera Gold Mine in Papua New Guinea, where a pyrite–arsenopyrite flotation concentrate is pressure leached. Flotation takes place at natural pH values, and PAX is the only collector. The frother is a mixture of MIBC and Dowfroth 400.

Feb 01, 1998 The EDTA-extractable copper of the new flotation feed during these surveys most closely resembles that of the monzodiorite ore, suggesting that chalcopyrite was the predominant copper mineral. This is also borne out by the relatively high fine copper recovery in the absence of sulphidisation (Survey 1, Figure 2) and the relatively unoxidised

Ore sorting: Efficiently optimise the treatment of ores in

By using ore sorting equipment, ore concentrates can be created at very low cost in small or remote mining installations. The entire processing line can be planned in semi-mobile form and consists only of crushers, screens, belts and sorting machines. This allows immense cost savings for transport, since the waste rock is disposed of on-site.

Investigation of the reasons for copper and gold loss in

Current operation (2003) is to blend 80% porphyry with 20% skarn ores, resulting in an acceptable concentrate grade and recovery. However, when the proportion of skarn ore in the plant feed exceeds 20%, low flotation recovery is often observed. Approximately 20% of the copper and 30% gold losses occur through the rougher flotation circuit.

Improving flotation efficiency

The new rotor produces ideal flow streams and an energy dissipation rate that enhances the bubble-particle attachment. The patented rotor/stator makes energy dissipation more uniform which results in a higher probability of bubble to particle contact during the flotation process.
