Any sandy component or quartz component of the original ore automatically carries through the smelting process as silicon dioxide.
23.
The charcoal is produced by heating wood to produce the nearly pure carbon fuel needed for the smelting process.
24.
The structure was built to disperse sulphur gases and other byproducts of the smelting process away from the city itself.
25.
During the copper smelting process, oxygen is deliberately injected into the melt to scavenge impurities that would otherwise degrade conductivity.
26.
The site also known as the Britannia smelting works was where the famous Imperial Smelting Process was developed.
27.
The size, scale and evidence of, now rare, smelting processes are preserved in the physical remains at the Chillagoe smelters.
28.
Before leaving the US, Chambers heard about a smelting process invented by Joel Wilson of Dover, New Jersey, which proved promising.
29.
Because of their location on the western sides of hilltops for use of wind in the smelting process they are named west-facing.
30.
Recovering the remaining ore became more expensive and the economics of the smelting process were adversely affected by the increasing cost of charcoal.
