In the first reaction of the first process, galena is roasted in order to remove the sulfur component of the metal sulfide. Roasting is a chemical reaction in which the sulfide ore is heated with abundant oxygen and the metal sulfide is either converted to a metal oxide or a metal. In this case, lead (II) oxide is produced along with sulfur ...
The main ores of copper are sulfides and oxides. From their chemical formulas you can calculate the percentage of copper in each mineral. However this is not the same as the percentage of copper in the ore as that also contains unwanted silicates and other minerals, called gangue, that will have to …
Mar 07, 2010· The conversion of the Iron ore to the metallic Iron is a chemical reduction, but depends upon the chemical nature of the ore being used, for example: 2 Fe2O3 + 3 C (as coke) ---> 4 Fe + 3 CO2 (g) This is actually a series of reactions that are temperature dependent. 3 Fe2O3 + CO ---> CO2 + 2 Fe3O4 (Begins at 850° F) Fe3O4 + CO ---> CO2 + 3 FeO ...

The reaction between silver sulfide and aluminum takes place when the two are in contact while they are immersed in a baking soda solution. As with almost all chemical reactions, the reaction is faster when the solution is warm. The solution carries the sulfur from the silver to the aluminum.
Steel - Steel - Primary steelmaking: In principle, steelmaking is a melting, purifying, and alloying process carried out at approximately 1,600° C (2,900° F) in molten conditions. Various chemical reactions are initiated, either in sequence or simultaneously, in order to arrive at specified chemical compositions and temperatures. Indeed, many of the reactions interfere with one another ...

ALUMINIUM EXTRACTION ALUMINIUM This page starts by looking at the extraction of aluminium from its ore, bauxite, including some economic and environmental issues. It finishes by looking at some uses of aluminium.
Several processes can then be used to separate the gold from the ore. The most common techniques in the United States use cyanide in various ways. In one, the ground ore is put into a tank containing a weak cyanide solution and zinc is added. The zinc causes a chemical reaction which separates the gold from the ore.
Silver chloride is a chemical compound with the chemical formula Ag Cl.This white crystalline solid is well known for its low solubility in water (this behavior being reminiscent of the chlorides of Tl + and Pb 2+).Upon illumination or heating, silver chloride converts to silver (and chlorine), which is signaled by grey to black or purplish coloration to some samples.
Mining produce ores containing 2% or less of copper. Concentrating the ore by froth flotation can result in ores with up to 35% copper. A collector oil, such as an organic xanthate or thiophosphate, is added to the powdered ore and adheres strongly to the chalcopyrite particles making them water repellant.
Yes, it is a chemical reaction. Smelting is melting the metal out of its ore. Most ores are a chemical compound of the metal with other elements, such as oxygen (as an oxide), sulfur (as a sulfide ...
In this chemical change the iron mineral is rendered more or less porous, thereby permitting the dissolution of the contained gold by subsequent cyanidation. Though simple in principle, considerable temperature and other controls are necessary to avoid undesirable side reactions …

Redox reaction of Fe 3+ (Reaction at room temperature for etching copper plates)
You can't make sulfur - it is an element, you can only mine, refine or produce it by chemical reaction. The majority of elemental sulfur in trade today is a byproduct of the petro-chemical ...
(For each of the following chemical reactions,write a word equation, a skeleton equation, and a balanced chemical equation. Be sure to show the state of each reactant and product. If you need more help writing formulas or determinging the state of a substance, refer to chapters 7 and 8 ant the periodic table on pages 178-179)
At this stage of the process, the chemical reactions begin. They convert the copper minerals into copper metal. We can illustrate the types of process using the example of chalcopyrite - CuFeS 2.From the formula, it is clear that iron and sulphur have to be removed in order to produce copper.
Extractive metallurgy is the practice of removing valuable metals from an ore and refining the extracted raw metals into a purer form. Hydrometallurgy uses aqueous solutions to extract metals from ores ( leaching ). Pyrometallurgy involves high temperature processes where chemical reactions take place.

Extracting of Copper from Other Ores. Copper can be extracted from non-sulfide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulfuric acid to produce a very dilute copper(II) sulfate solution.
Silver: silver ores may be detected by dissolving a small quantity in a test tube with a few drops of nitric acid. Boil until all the red fumes disappear. Let the solution cool, and add a little water. Filter the whole, and add a few drops of muriatic acid, which will precipitate the white chloride of silver. Dissolve this precipitate with ...
The extraction of aluminium involves two steps that is, purification of bauxite by Baeyer's process and 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 meta aluminate.
Silver: Silver is generally found in serpentine, trap, sandstone, limestone, shale, or porphyry rocks, the gangue being quartz, calc, fluorite, or barite.All silver ores are heavy, and many of them are sectile, i.e., may be cut with the knife. Western men test for silver by heating the ore and dipping it into water.
