The reactivity series and metal extraction The reactivity of a metal determines how it is extracted. Metals above carbon in the reactivity series must be extracted using electrolysis. Metals less reactive than carbon can be extracted from their ores by reduction. Copper, silver, gold and platinum can occur in their pure form (natively) and do not

Electrolytic Gold Extraction Experiment Ore from Colorado number "A". This ore is a "rotten granite" containing a very small amount of sulphide, no telluride, a little copper and considerable iron as oxide. The gold is in a very fine state of division.
Gold parting is the separating of gold from and silver are often extracted from the same ores and are chemically similar and therefore hard to separate. Over the centuries special means of separation have been invented. The very earliest precious metals had mixes of gold and silver; gold and silver alloy is called the advent of coinage, methods had to be invented to ...
There are several methods for how to recover platinum from catalytic converters, and other metals, too. But in most cases, the assistance of professionals might be more beneficial. But if you wish to extract it yourself, you can follow this procedure:
Platinum is an incredibly rare metal that is mined and extracted in a variety of different ways depending on the technological sophistication of the miners attempting to extract it. It is incredibly difficult to find in large pure quantities, so it needs to be extracted from the ore in a very specific way.

Gold from ocean? Extraction from seawater . Extraction of gold from seawater. Here''s the basic current problem with electrolysis as a recovery technology: you connect a generator or battery to your electrodes and start pumping electrons from the anode to the cathode through the wiring.
The key process of electrolysis is the interchange of atoms and ions by the removal or addition of electrons from the external circuit. The desired products of electrolysis are often in a different physical state from the electrolyte and can be removed by some physical processes.
It is a method of making pure gold as in the past and is popularly used in ancient times Up until now. Extraction of gold by smelting is done with metallic mix gold. Scrap gold, jewelry gold, with gold components for more than 25%. Not suitable for metal gold plated surfaces. Ratio Gold alloy 1 Copper 1 Lead 2 1. Melt Metal all together.
But the amount of gold in the earth is extremely small, so that mining is not really worthwhile. Generally there are two types of gold: primary gold ("mountain gold" from mines) and secondary gold ("stream gold", "nuggets"). Above all the extraction of primary gold is associated with considerable effort.
Platinum is rarely found on its own, but in combination with other base and precious metals. Extraction of the pure metal from ores is a complex process, and includes milling the ore, a froth ...
Gold and platinum are among the world''s most valuable substances. Traded daily on major commodities exchanges, their worth often approaches or exceeds 1000 an ounce. Gold is an ancient staple of jewelry and ornament. Platinum, too, is a perfect setting .

The earlier stages of the mining and recovery of the platinum metals from the Rustenburg Platinum Mines have been reviewed in some detail in this journal (), while the geology of the Bushveld Igneous Complex and the platinum reefs—constituting an enormous reserve of platinum metals—which are mined by the Rustenburg company has also been described ().
Metals above carbon in the reactivity series must be extracted using electrolysis, Metals less reactive than carbon can be extracted from their ores by reduction, Copper, silver, gold and platinum can occur native and do not need to be extracted. Sometimes copper needs to be extracted from an ore.
sulphur. The platinum group metals, together with some gold, total about fifty ounces to the ton. The complete process of extraction consists essentially of enriching this matte to approximately 65 per cent content of platinum metals and then treating this concentrate with acids to separate the

Bromine acts more energetically than chlorine, and has also been employed in the extraction. The recovery of the gold is effected similarly, and the bromine is then liberated by the action of chlorine, but it is impossible to prevent loss of bromine. Cyanideprocess The extraction of gold by the cyanidemethod is of great technical importance.
