Copper -- Metallurgy

The above description is quite general, several details for certain
classes of ore having been omitted, but it gives a fair idea of the
general principles underlying such work.

The final sample, say 3,200 lbs. per 1,000 tons of ore, is mixed on an
iron plate on the floor, quartered several times by a Brunton shovel,
and the chosen sample then ground in an Englehardt mill (small Gates’
crusher with two discharges). The material is passed through a 1-foot
riddle of 100 mesh wire cloth, the very small quantity of coarser stuff
remaining, is bucked down and added, and the whole is then thoroughly
mixed in a canister of 1 foot side gripped at opposite corners, and
rotated mechanically.

        of Ores: Concentration, Briquetting, Sintering — The
        Principles of Copper Smelting — Roasting.


=Modern Copper Smelting Practice.=—Until recently, modern smelting
practice has been understood to involve the production of a matte
containing from 40 to 50 per cent. of copper, which is then
bessemerised.
