    Extracting Lead Materials from Ore

    Usually, lead is found in conjunction with other metals such as silver and zinc. Lead materials are mined as a by product of these other more valuable metals. Extracting the lead materials from the ore is a multi-step process. First the lead ore is ground into small particles that are less than 0.1mm, giving the ore a texture similar to table salt.Gold Smelting Process | SciencingApr 24, 2017· Gold ore extracted from mines in the earth contains a significant amount of impurities, including traces of other metals. In order to separate the gold from other metals, chemicals such as cyanide solution or mercury are introduced to the gold. This process causes the gold to coagulate, and form nuggets and clumps of gold.The soluble complex formed during the extraction of silver ...In cyamide extraction process of silver from argentite ore, the oxidising and reducing agents are respectively. View Answer In the extraction of silver by Mac-Arther cyanide process, a small amount of K N O 3 is also added as flux.People Extracting Gold From Copper OreExtracting gold howstuffworks the lifecycle of a gold mine people in hard hats working underground is what often comes to mind when thinking about how gold is mined yet mining the ore is just one stage in a long and complex gold mining process long before any gold can be extracted, significant exploration and development needs to take.

The process of extraction of silver is called as cyanide process as sodium cyanide solution is used. The ore is crushed, concentrated and then treated with sodium cyanide solution. This reaction forms sodium argento cyanide (Na [Ag(CN)_2]).Smelting and Roasting Ores to recover gold, silver and ...The process works best when the ore is crushed to small pieces before roasting. Additives, such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides. Once the ores are fully roasted, and the sulfur is driven off, the extraction of the gold or silver from the ore is not especially difficult.
