Magnetic separation makes use of magnetic differences between minerals to separate material, which occupies a very important position in iron ore separation field. Magnetic separating plant has the advantages of energy saving, high efficiency and high

Calcium carbonate is the main raw material to make cement, lime and calcium carbide, and it is an indispensable flux limestone in metallurgical industry.

Powder grinding plant is generally composed of jaw crusher, bucket elevator, electro-vibrating feeder, mainframe and auxiliary engine of grinding mill, draught fan, dust-removing equipment, centralized electronic control and other equipment. According to

Abstract A strange unidentified Cu‐Fe bearing zinc sulfide occurs in the Laloki massive sulfide deposit Papua New Guinea The mineral is optically uniform in texture but is chemically variable and zoned even within a single grain Copper contents vary from 01 up to 885 wt

The Mt Sisa Orebody on Misima Island PNG consists of goldsilver mineralization associated with massive carbonate and amor phous ironmanganese oxides in fractures and breccia matrix The orebody forms the north ern extension of the Umuna deposit The mineralization lies within the three kilometre strike length of a northwest trending 300 metre wide high angle

Developments in Milling Practice at the LeadZinc Concentrator of Mount Isa Mines Limited from 1990 MF Young1 JD Pease2 NW Johnson3 and PD Munro4 Submitted for AusIMM Sixth Mill Operators Conference 68 October 1997 Madang Papua New Guinea ABSTRACT

The temperature of mineralization ranges from 230280E8249C Bulk chemical composition of the ore samples indicates that the mineralization in the Pacmanus site can be classified into the ZnCuPbAu type The mineral assemblage character of the ores and tectonic setting resembles those of ancient Kuroko and currently forming hydrothermal

Australias mineral deposits are described in the AUSIMM monographs on the Geology and Mineral Deposits of Australia and Papua New Guinea Solomon and Groves 1994 updated 2000 provide a comprehensive synthesis of the geology and origin of Australias mineral deposits

For example zinc sulphate cyanide and sodium sulphide are usually added to grinding circuits prior to CuPb flotation to avoid activation of sphalerite and pyrite during grinding However there have been no systematic studies on the effect of grinding conditions on mineral activation

This region is in the centre of the New Guinea Orogen an extensive geological zone that makes up the mountainous spine of Papua New Guinea The western portion of this zone encompasses the world class mining operations of Porgera OK Tedi WafiGolpu and Grasberg
