How Is Platinum Extracted? | Reference

It can take up to 6 months and 7 to 12 tons of ore to produce 31.135g of pure platinum.. STEPS INVOLVED : The first step in the production process is to break platinum containing ore and immerse it in indicator containing water, a process known as 'froth flotation'.

Purification of Platinum. Preliminary treatment of the ore or base metal byproduct with aqua regia (a mixture of hydrochloric acid, HCl, and nitric acid, HNO3) gives a solution containing complexes of gold and palladium as well as H2PtCl6. The gold is removed from this solution as a precipitate by treatment with iron chloride (FeCl2).

Gold processing, preparation of the ore for use in various products.. For thousands of years the word gold has connoted something of beauty or value. These images are derived from two properties of gold, its colour and its chemical stability.The colour of gold is due to the electronic structure of the gold atom, which absorbs electromagnetic radiation with wavelengths less than 5600 angstroms ...

The Extraction of Iron

Silver processing, preparation of the ore for use in various products.. Silver has long been valued for its white metallic lustre, its ability to be readily worked, and its resistance to the corrosive effects of moisture and oxygen.The lustre of the pure metal is due to its electron configuration, which results in its reflecting all electromagnetic radiation of wavelengths longer than 3000 ...

How To Use Aqua Regia To Purify Gold

A slurry of ground ore, water and a weak cyanide solution is fed into large steel leach tanks where the gold and silver are dissolved. Following this leaching process the slurry passes through six adsorption tanks containing carbon granules which adsorb the gold and silver. This process removes 93% of the gold and 70% of the silver.

how to process platinum ore

As Platinum is so incredibly rare it can take about as much as 10 tonnes of ore to find one ounce of Platinum. There are several steps in the mining process of Platinum, the first one being extraction of the Platinum ore and bringing it above ground, there are two ways of doing this the first and older way is to blast the ore free with explosives.

Purification Of Late Transition Elements Or Compounds ...

Gold Purification Using Acid. Using acid for purifying gold is the most common and simplest approach to removing any impurities from this precious metal. Two common types of acid used for refining gold are hydrochloric acid and nitric acid. These two acids are mixed in a beaker to create the purifying solution.

How is platinum extracted from its ore

The extraction of aluminium involves two steps:-1. Purification of bauxite by Baeyer's process. 2. Electrolysis of alumina. 1. Purification of bauxite by Baeyer's process:-In the Baeyer's process, the bauxite ore is heated with concentrated NaOH solution under pressure (Aluminum is purified by leaching method). The alumina dissolves as sodium ...

The Six Main Steps of Iron Ore Processing | Multotec Canada

Refractory ore contains carbon and is heated to over 1000 degrees F, which removes sulfide and carbon. The resulting oxide ore is directed to the leaching circuit. Sulfide refractory ore that contains no carbon is oxidized in an autoclave to free gold from sulfide minerals, then it is sent to the leaching circuit.

The Properties and Applications of Platinum

This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile. The aim of this step is to ensure a smooth crushing process and minimize downtime in the event of a breakdown or to allow planned maintenance in the crushing system, without stopping the ...

step in extracting purifying gold 」

Refining gold from ore or concentrates is done during the smelting process. During this process, flux is used to dissolve contaminates such as metal oxides from the gold. The flux is added to a crucible with the gold that is then melted in a furnace. You can make flux for gold refining by first obtaining all of the ...
