The ore is usually brown, a metallic iron color, or mixed with a large white quartz rock that has very little gold in it. Gold ore may not be easily recognizable to the untrained eye. Fortunately, gold has many distinguishing characteristics, such as its heavyweight .
and gold. The most common lead ore mineral is galena, or lead sulfide . Another ore mineral in which lead is found combined with sulfur is anglesite or lead sulfate . Cerussite is a mineral that is a carbonate of lead. All three of these ores are found in the United States, which is one of the chief lead mining countries.
This is a substance added to a material to aid in its fusion. Other action is to act as a reducing agent to dioxide or decompose impurities and remove them as slags. In this way, we can insure complete decomposition of the ore. One of the components is a lead oxide that is reduced to metallic lead. This metallic element collects gold and silver.
While it may never be commonplace to transmute lead into gold, it is practical to obtain gold from lead ores. The minerals galena , cerussite , and anglesite often contain zinc, gold, silver, and other metals. Once the ore has been pulverized, chemical techniques are sufficient to separate the gold from the lead.Chemistry Expert
RECOVERY OF SILVER, GOLD, AND LEAD FROM A COMPLEX SULFIDE ORE USING FERRIC CHLORIDE, THIOUREA, AND BRINE LEACH SOLUTIONS By R. G. Sandberg 1 and J. L. Huiatt 2 ABSTRACT The Bureau of Mines investigated a hydrometallurgical procedure to re cover gold, silver, and byproduct lead from a complex lead zinc sulfide ore.
The lead and copper must be removed in bulk as a mixed concentrate and then the zinc floated as a separate concentrate because of marketing requirements. A further separation of the lead copper into their respective products by flotation is often economically advantageous if the crude ore contains 0.8% copper or more.
