This gangue is dug out and broken up as in mines of other metals.
3
The non-magnetic gangue descends in a straight line to the other side of the partition.
4
Metallic mercury is easily volatilized, and separated from the gangue, at temperatures far below redness.
5
This is variously described as "insoluble," "sand," "insoluble silicates," "gangue," or "rocky matter."
6
And that with ores almost free from gangue some quartz or glass should be added to protect the crucible.
7
The second includes the trituration of the gangue and the extraction of its gold or silver by means of mercury.
8
A description of the process is as follows:-Theore is crushed to a certain fineness, depending on the character of the gangue.
9
Careful dissolving of the pyrites and gangue, so as to leave the gold intact, failed to find it in any larger diameter.
10
Lewis rode over the mountains last fall, which horse was Seen yesterday with a gangue of Indian horses, and is Very wild-.
11
The first point, then, is to crush the gangue effectively, the degree of fineness being regulated by the fineness of the gold itself.
12

13
Pécuchet brought him over to the side of the cliff to show him a serpent-stone incrusted in the rock, like a diamond in its gangue.
14
The surface of the isolated specimens is well defined, and their separation from the gangue (which has never been penetrated) is of the easiest character.
15
Hence the elimination of the worthless "gangue" by concentration of the iron particles associated with it, seemed to be the only solution of the problem.
