In 1883, Charles Rasp discovered at Broken Hill heavy rocks which he thought may contain tin. Subsequent assays (chemical analysis) of these rocks proved that he had located rich oxidised (weathered) silver and lead minerals. Ore is still being extracted from Broken Hill, which has been the largest producer of lead-zinc-silver in Australia.

Galena Mineral | Uses and Properties

Galena value: Some mines produce more revenue from the silver content of their galena than from the lead content. Assume that we have a mine that produces argentiferous galena with an average composition of 86% lead, 13% sulfur and just 1% silver (as shown in the diagram on the left).

Silver Gold Recovery Flotation Process

Thus, in a lead-zinc ore, silver is more valuable in the lead than in the zinc concentrate. Similarly, in a copper or lead ore carrying gold associated with pyrite, it might be profitable to make an iron concentrate containing the gold. If the gold and silver can only be brought up in the desired concentrate by contaminating it with unwanted .

All silver ores need to be fluxed for smelting.6 In Pliny's day, when almost all the ore smelted was high-grade, the addition of lead or lead ore (galena, PbS) was sufficient for fluxing (book XXXIII, sec. XXXI). By the time that Biringuccio and Agricola are writing in the 16th century, the art of fluxing has advanced in complexity but not in .

What Is a List of Soft Metals? | Reference

According to the Mohs hardness scale, a list of soft metals includes lead, gold, silver, tin, zinc, aluminum, thorium, copper, brass and bronze. Gallium might also be considered a soft metal, as it melts at 85.57 degrees Fahrenheit. Mercury is a metal that's liquid at room temperature. In many cases, a metal's softness is what makes it valuable.

Chapter 2157 Кб. Ores with half that silver content, enriched to the optimal level of silver concentration, produced in the hearth a 'hard' lead, which in refining was only partially converted into lithage.The effectiveness of this operation, however, diminished as the 'hardness' of 'fertile' lead increased.
