Platinum is a dense, stable and rare metal that is often used in jewelry for its attractive, silver-like appearance, as well as in medical, electronic, and chemical applications due to its various and unique chemical and physical properties. Platinum metal has a number of useful properties, which
Because platinum is so rare, it must be extracted after being mined through a process that involves crushing it into incredibly small particles and separating these particles from one another. This is known as the flotation separation method, and produces a frothy layer of particles that can be
How is platinum extracted from its ore 1. How is platinum extracted from its Ore? An ore is a naturally occurring mineral from which a pure metal can be extracted. For Platinum, the two- chief minerals are sperrylite or platinum arsenide (PtAs2) and co ...
The platinum ores were mostly processed by traditional milling and gravity-table concentration. Flotation was used for the first time to produce a sulphide platinum concentrate in 1926, at Potgietersrus. 28 The weakening of the platinum price in the early 1930s ...
Best Answer: In order to obtain platinum from its ore, the rock is crushed, made into a slurry, and then mixed with a detergent containing 'collector' molecules. Air is then blown through the mixture, enabling the grains of metal minerals to be separated from ...
How Is Platinum Mined : Platinum in its raw state is very rare and is one of the more costly of the precious metals, a fact that is certainly reflected in the price of platinum jewelry. In addition to jewelry, platinum is used by many industries, including electronics and ...
Jewelry! :) Platinum is one of the best metals for jewelry-use because it is durable and hypoallergenic. It is so strong on its own that it has to be mixed in with other metals to make it more malleable. In jewelry, high-grade platinum pieces usu...
Platinum History Platinum was discovered by early Spanish explorers in Columbia and finally brought back to Europe in 1735. When Platinum was first discovered, people did not know what to do with it so they called it Platina meaning Silver of little value. The native ...
What is platinum? Platinum is a precious heavy metal. Because it is both dense and malleable, it is ideal in jewelry production. Platinum derives its name from the Spanish ... Why buy platinum vs. white gold or sterling silver? Platinum is extremely rare. Though it ...
They used a gold-platinum alloy for making ornaments and jewelry. Platinum is not abundantly found in earth’s crust and that is why a very small amount is produced every year. The average abundance of platinum in earth’s crust is 5µg/kg. It has a melting point of ...
Titanium processing: Titanium processing, the extraction of titanium from its ores and the preparation of titanium alloys or compounds for use in various products. Titanium (Ti) is a soft, ductile, silvery gray metal with a melting point of 1,675 C (3,047 F). Owing to ...
Platinum is a transition metal in Group 10 (VIIIB) of the periodic table. The periodic table is a chart that shows how chemical elements are related to each other. Platinum is also a member of a group of metals named after itself. Other platinum metals include ruthenium, rhodium, palladium, osmium

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 floatation process, and smelting at high temperatures. This removes base metals, notably iron and sulfur
Processing & Refining Crude Oil Refinery Products Projects History Chevron's Pascagoula Refinery processes 330,000 barrels ... Because about 80 percent of the crude oil processed by the Pascagoula Refinery is heavier oils that are high in sulfur and nitrogen ...
Ore leaves the mine to be refined. The first step in the mining process is getting the platinum ore out of the ground and into a refinery or processing plant. Two methods exist to extract platinum ore: the old "narrow reef method" and newer mechanical mining methods. The original "narrow reef method
