High cartage costs to the mill and water supply were problems, as was the old and troublesome ball mill, whereas the company's molybdenite plant, erected for the separation of quartz and molybdenite with aid of oily water, was a model of simplicity.

Demand for high grade wolfram, after the development of tungsten as a lamp filament in 1904, and for molybdenite for use in patent alloys, led to an early interest in rare minerals by British firms, the most prominent being George G . Blackwell and Sons of Liverpool.

To separate the molybdenite from the copper sulfides, the copper / molybdenum concentrate is run through a molybdenite recovery flotation circuit, in which chemicals are added to " depress " the copper, meaning to prevent the copper sulfide minerals from attaching to the froth, while the molybdenum is unaffected.

Minerals in the Temagami area include Aragonite, Brochantite, Calcite, Chalcopyrite, Jasper, Magnetite, Molybdenite, Pentlandite, Pyrite, Pyrrhotite, telluride mineral was discovered on Temagami Island in 1973 called temagamite, named after its discovery locality in Copperfield's Mine, originally known as Temagami Mine.

Demand for high grade wolfram, after the development of tungsten as a lamp filament in 1904, and for molybdenite for use in patent alloys, led to an early interest in New Zealand Loan and Mercantile Agency and W . J . Lempriere and Co, but generally the local industry was poorly organised.

In 1963, Soviet scientist Victor Cherdyntsev, who had previously claimed the existence of primordial curium-247, claimed to have discovered element 108 ( specifically, the 267 Hs isotope, which supposedly had a half life of 400 to 500 million years ) in natural molybdenite and suggested the name " sergenium " ( symbol Sg; at the time, this symbol had not yet been taken by seaborgium ) for it, after the ancient city of Serik along the Silk Road in Kazakhstan where his molybdenite samples came from.

The motivation of many of the research projects pursued under his guidance was to find innovative means of beneficiating several complex and / or low-grade Indian mineral deposits, such as monazite beach sand, zircon, molybdenite, diamond, phos�phorites, zinc ferrite, zinc tailings and residues, alumina-rich iron ore, pyrite, separation amongst calcium mineral systems, Kudremukh-iron ore tailing, deep sea manganese nodules, ferrotungsten deposits etc . Simultaneous studies were also carried out in his laboratory on several key unit operations in mineral processing, such as comminution, froth flotation, selective flocculation, leaching and bacterial leaching.
