NATIVE LEAD (Pb) - Amethyst Galleries
The lead ore contained a significant percentage of silver, and was mined for that purpose and led to the founding of the mining town, Leadville. In addition to producing 240,000 ounces of silver, the mines produced nearly a billion tons of lead and more than a half-billion tons of zinc.

Ore Hardness Testing -SAG Mill Tonnage Estimation Method
For design purposes, you need an estimation or prediction of your SAG Mill’s tonnage; well, there are 3 ways to generate good rock “ore” hardness testing data for SAG and ball mill circuit grindability from half drill core. We can abbreviate the discussion by saying there are three “religions” of grinding, and there are small-scale tests suitable for all three of the major religions ...

A precipitate appears. It may be silver, lead or mercury. - If silver, it grows dark violet after exposure to sunlight, or 30 or 40 drops of ammonia dissolves it in a few moments. Should it not dissolve, it is lead or mercury. Test for lead by filtering, and heating some of the precipitate on charcoal before the blow-pipe.

SYLVANITE (Silver Gold Telluride)
Sylvanite is one of the few minerals that is an ore of gold, besides native gold itself. It is one of the most common gold bearing minerals. The element gold is typically either found as native gold (in its elemental state), as an alloy with other metals such as silver and copper and as trace amounts in a few minerals.
