Report on extraction of metals of low reactivity silver

) Low reactivity metals like silver, mercury, platinum and gold are after sound in free state. 2) Their reactivity with other atoms is very low. 3) Oxides of these metals can be reduced to metals by heat alone and sometimes by displacement from their aqueous solution.

The Metal Reactivity Series | Compound Interest

The metals designated as the transition metals in the periodic table are much less reactive, and metals such as gold and platinum prop up the bottom of the series, exhibiting little in the way of chemical reaction with any everyday reagents.

THE RECOVERY OF PLATINUM, PALLADIUM, AND GOLD

Gold was selectively recovered with the use of Minix, while effective recovery of gold, platinum, and palladium over the base metals, copper, and iron, was achieved with Amberlite PWA-5. Successful elution of these metal cyanides was possible from both Minix and Amberlite PWA-5,

Extraction of Metals of Least Reactivity

Extraction of Metals of middle reactivity: Iron, zinc, lead, etc. are found in the form of carbonate or sulphide ores. Carbonate or sulphide ores of metals are first converted into respective oxides and then oxides are reduced to respective metals.

Separating the Platinum Group Metals by Liquid-Liquid

The platinum group metals platinum, palladium, rhodium, iridium, osmium and ruthenium together with silver and gold generally occur in nature associated with the major base metals iron, copper, nickel and cobalt and a wide range of minor elements such as lead, tellurium, selenium and arsenic, and

PlatinumWikipedia

During electrorefining of copper, noble metals such as silver, gold and the platinum-group metals as well as selenium and tellurium settle to the bottom of the cell as "anode mud", which forms the starting point for the extraction of the platinum-group metals.
