Silver Processing From Lead Concentrates

Dec 18 2016 In some places it is produced by the Parkes Process used to refine lead bullion. Silver meant for commercial purposes must be at least 99.9 pure. Mexico which was the leading silver producer in the world in 2015 has produced silver since 1546. The top five silver producers in the world include Mexico Peru Australia Bolivia and China. .

    Recovery of Gold as ByProduct from the BaseMetals

    Jan 01 2016 As an example from a lead concentrate assaying 133 gt Ag and 0.7 gt Au 99 and 97 respectively of the silver and gold are recovered in the lead bullion in Tsumeb Mounsey and Piret 2000. The bullion is then processed to metallic lead using either thermal or electrometallurgical techniques Siegmund 2000 as illustrated in Figure 46.18 .

    Silver Lead Zinc Ore Processing Method using Flotation

    Apr 20 2016 The process consists of selective flotation to produce a mixed silver-lead concentrate for maximum smelter return and a separate zinc concentrate. Over-grinding of silver minerals is detrimental to efficient flotation recovery so the Flash Flotation Unit-Cell is used in the grinding circuit to recover a large part of the silver and lead values as soon as liberated.

    How silver is made material making history used

    Silver is rarely found alone but mostly in ores which also contain lead copper gold and other metals which may be commercially valuable. Silver emerges as a byproduct of processing these metals. To recover silver from zinc-bearing ores the Parkes process is used. In this method the ore is heated until it becomes molten.

    Smelting and Roasting Ores to recover gold silver and

    This is handy when processing silver containing minerals to convert them to silver metal. The addition of scrap iron to smelt mixes is a useful technique to small-scale operators experimenting with smelting techniques on gold-silver ores. It could also be used with small lots of sulfide concentrates.

    Thiourea leaching of the hematitelead jarosite product extracted only 46–88 of the gold and 1–7 of the silver with thiourea consumptions of 8–70 kgt thiourea. Thiourea leaching of the basic iron sulphatelead sulphate product extracted 83–92 of the gold and 39–96 of the silver with thiourea consumptions of 33–132 kgt.

    The Froth flotation process separates the Lead and other minerals from the waste rock tailings to form a concentrate. The concentrate which can range from 50 to 60 Lead is dried and then treated using pyrometallurgy. The concentrate is sintered before being smelted in to produce a 97 Lead concentrate.

Smelters typically pay 95 Au and 90 Ag in copper and lead concentrates but will only pay 60-70 maximum depending on degree of PbZn smelter integration for gold and silver in zinc concentrates. Cost drivers are also important in flowsheet selection and are summarised in Table 3.
