How Metals are Made

The most common ore used for aluminum production is bauxite, a claylike substance that is around 50 percent alumina—aluminum bonded with oxygen. As with iron, getting to the aluminum means getting rid of the oxygen and the minerals in the ore. The process is much more complicated than iron extraction, and was only developed in the late 1800s.

Tin processing Britannica

Tin processing, preparation of the ore for use in various products.. Tin (Sn) is a relatively soft and ductile metal with a silvery white colour. It has a density of 7.29 grams per cubic centimetre, a low melting point of 231.88 °C (449.38 °F), and a high boiling point of 2,625 °C (4,757 °F). Tin is allotropic; that is, it takes on more than one form.

Gold processing Britannica

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

Iron processing Britannica

Iron processing, use of a smelting process to turn the ore into a form from which products can be fashioned.Included in this article also is a discussion of the mining of iron and of its preparation for smelting.

Jun 05, 2015· Iron ore, coke and limestone are fed into the furnace from the top and gradually sink down towards the bottom, getting hotter as they descend. In the top half of the furnace, gas from the burning coke releases oxygen from the iron ore. In the bottom half of the furnace, limestone starts to react with the impurities in the ore and coke forming a

Precious Metal Ores, Gold, Platinum, Silver and Copper

By ore mineral is meant a metalliferous mineral which owes its economic value to the fact that it is smelted or otherwise processed to obtain a useful metal. A large number of economic minerals however, require treatment to be concentrated (i.e. separated from the matrix) before the minerals are available for smelting or other processing to

Mining and Mineral Use Earth Science

An ore is a rock that contains minerals with useful elements. Aluminum in bauxite ore ( Figure below) is extracted from the ground and refined to be used in aluminum foil and many other products. The cost of creating a product from a mineral depends on how abundant the mineral is and how much the extraction and refining processes cost.

The Properties and Applications of Platinum

Aug 21, 2020· Extracting platinum from ore is both capital and labor-intensive. It can take up to 6 months and 7 to 12 tons of ore to produce one troy ounce (31.135g) of pure platinum. The first step in this process is to crush platinum containing ore and immerse it in the reagent containing water; a process known as 'froth flotation'.

Iron Ore HowStuffWorks

To get to the bits of iron in the ore, you have to smelt it out. Smelting involves heating up ore until the metal becomes spongy and the chemical compounds in the ore begin to break down. Most important, it releases oxygen from the iron ore, which makes up a high percentage of common iron ores.
