Assertion: Platinum (Pt), gold (Au), and silver (Ag) are native elements that are found freely in the earth's crust. Platinum For the following reasons, jewellery is made of gold and silver. They are extremely shiny metals that don't corrode. They may be moulded into any shape or pattern due to their extreme malleability and ductility.
Metal Extraction in the Middle of the Reactivity Series
Gold, platinum, and silver are the three least reactive metals. By heating alone, low-reactive metals can be reduced to metals. Thermal decomposition is the extraction process used to obtain these metals. The less stable an oxide or compound a metal forms, the easier it is to extract. Low-reactive metals, or metals found at the …

Extraction of Metals: Methods, Processes Involved, …
The metals at the bottom of the activity series are the least reactive. They are often found in a free state. ... For example, gold, silver, platinum and copper are found in the free state. ... Extracting Metals Low in the Reactivity Series . Metals low in the activity series are very unreactive. The oxides of these metals can be reduced to ...
Extraction of Metals: Methods, Processes Involved, Minerals, …
Different separation techniques are accordingly employed. 1. Extracting Metals Low in the Reactivity Series.
Metal Extraction in the Middle of the Reactivity Series
The low-reactivity metals include copper (Cu), mercury (Hg), silver (Ag), platinum (Pt), and gold (Au). These metals' inertness allows their oxides to be …
Occurrence of Metals: Metal Ores, Methods of Extraction, …
Metals of low reactivity level. Metals that aren't very reactive are placed low in the reactivity series. These metals can be reduced to metals by heating alone. For example, Mercury is procured from its ore, cinnabar (HgS), by the process of heating. Copper can also be obtained from its sulphide ore (Cu 2 S) by heating.
Extraction of Metals – Concentration, Reduction and Refining
Low reacting metals: These metals are free to state metals and less reactive than other options. The extraction of metals with such property is very easy and cost-effective. …

Extraction of gold from platinum group metal (PGM) ores
3.3. Selective reduction of gold in PGM solutions. The classic process involving reduction of gold to metal from chloride solution is a simple and effective process that is well suited to batch operation. A large number of reagents have been used, namely hydrazine, SO 2 gas, oxalic acid, bi sulfite, sucrose and others.

The activity series of metals or reactivity series is a list of metals from most reactive to least reactive. Knowing the activity series helps you predict whether or not a …
Reactivity series of metals
Learners may have a misconception that acid–metal reactions occur because the acid 'eats away' at the metal as this is their understanding of the term 'corrosive'. Address the misconception by demonstrating that metals less reactive than hydrogen (copper, silver, gold, platinum) will not react with acid. Reinforce the process of
Guide to Platinum | Key Properties & Uses | BullionVault
Chemical properties of platinum. Platinum has the chemical symbol Pt and its atomic number is 78. It is silverish white in colour and dense, malleable and highly unreactive. A member of the platinum group of metals, it has six naturally occurring isotopes and has a natural resistance to corrosion, not oxidising in the air even at high temperatures.
