Several methods are used to extract silver from different ores. For maximum efficiency, the method is geared to the nature of the ore. In the 16 th century, the huge silver …

explaining how to refine silver for silversmithing. This is the consequence of a rather subtle fact, namely that refining silver is identical to the cupellation of silver for assay, which in turn is identical to the parting of silver and lead in the lead reduction smelting process. The only difference between these three things is one of scale.

The methods for refining metals vary according to the type and use of the metals. Refining merely refers to as purification. Thus, metal refining removes the gangue particles or matrix from the metals obtained through the various reduction processes and gives a pure or refined metal.

Two (2) major techniques for refining gold. Generally, gold can be refined using these two-best-known gold-refining procedures: Aqua Regia and gold electrolysis. Both of these techniques can be used to separate gold from other metals. This is because a little piece of other metals in gold can change its properties and value.

Silver derived from copper and its derivatives, including copper sulfide, requires different handling and refining techniques than silver minerals taken from zinc deposits and lead sources. These metals have different physical properties, which accounts for the different methods …

Apr 23 2014. Electrolysis, or electrolytic refining, is a technique used for extraction, as well as purification, of metals obtained by any refining method. In the electro-refining process, a block of impure metal becomes the anode, and a thin sheet of metal becomes the cathode. Both the cathode and anode are dipped in an electrolytic cell ...

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.

Electrolytic Refining. This is one of the most common and widely used methods because it is applicable to most metals. In this method, we use the different electrochemical properties of the metals and the impurities to our advantage. In this process, the impure metal is the anode. The cathode is a …

Equally important, as early as the 1550s, miners in Mexico developed the amalgamation process, a cheap, simple method of refining large quantities of low-grade silver ore. In the years immediately following the discovery of Potosí in Upper Peru, Indians smelted its rich ores in their own clay furnaces.
