Copper Ore Dressing |
This diagram
has been constructed based on the written description given in Bryan Earl
in his excellent book "Cornish Mining". It has simplified some of the possible
material flows but does show the basic features of a Victorian mine's Copper
Ore dressing process. Size reduction operations are shown in yellow and
classification/ concentration operations in blue .
Hand sorting (picking) of was a feature of Copper dressing and it arose from the Ores characteristic of breaking into a fine powder when stamped. This trait that made stamped ore difficult to treat without causing excess losses. Other more complex ore processing diagrams do exist but this model will explain the basic layout of most Copper mine dressing floors. |
A simplified
diagram of the copper dressing process.
The terms explained
The Halvan processing was
a series of water based functions whilst Drage dressing relied heavily
on manual labour . Wherever
possible copper ore was separated from the gangue by hand. This hand picking
occurred underground and within the dressing floors.
