Ores are the concentration of any mineral with other elements, found in a particular area, in the form of rocks.The extraction of minerals can be done by mining, drilling and quarrying.This article will help you understand the substantial differences between metallic and non-metallic minerals.
Metals like iron, silver and copper get corroded on exposure to air.Write the chemical name of the substance deposited on their surface respectively with its colour, in each case.Question 22 a define the term alloy.Write two advantages of making alloys.
Zeolite ores treating.Zeolite - wikipedia.Zeolite-based oxygen concentrator systems are widely used to produce medical-grade oxygen.The zeolite is used as a molecular sieve to create purified oxygen from air using its ability to trap impurities, in a process involving the adsorption of nitrogen, leaving highly purified oxygen and up to 5 argon.
Chemical or scientific names are used to give an accurate description of a substances composition.Even so, you rarely ask someone to pass the sodium chloride at the dinner table.Its important to remember that common names are inaccurate and vary from one place and time to another.
Copper is a naturally hygienic metal that slows down the growth of germs such as e-coli the burger bug, mrsa the hospital superbug and legionella.This is important for applications such as food preparation, hospitals, coins see biocidal copper , door knobs and plumbing systems.
An alloy is a material made by melting one or more metals together with other elements.This is an alphabetical list of alloys grouped according to base metal.Some alloys are listed under more than one element, since the composition of the alloy may vary such that one element is present in a higher concentration than the others.
When we study the elements, it is important to know which elements are metals and which ones are not.If you are trying to learn to distinguish between metals and non-metals, a list and their uses is a good way to break them down and help memorize the difference between the two.
Shows the names and symbols of the elements.A chemical symbol consists of one or two letters always starts with a capital letter, with any other letter in lower case.

Copper is an example of this.Copper mostly occurs as sulfide ores, which are heated in air to convert them to copperii oxide.Molten copper can be produced from copper.
Extraction of metals.Extraction of copper.Copper is sometimes found as native metal.Copper ores include copperii oxide and copperii sulfide.Copperii oxide can be reduced by reaction with carbon.Some copper ores may contain only small amounts of copper.These are called low grade ores and have less than 1 copper but they are still used because copper is so valuable.
The discovery of copper in 5,000 bc marked the end of the stone age and the beginning of the copper age.The later invention of bronze , an alloy of copper and tin, started the bronze age.The use of ferrous metals started in around 1,200 bc when iron production started to become commonplace.
Currently, almost any object produced by the use of technology uses metals in one or other forms.Modern man has also learned how to use the combination of metals, i., alloys for his benefit.So the use of metals in our daily life has become inevitable.Hence we can see that these are some of the highest-priced commodities in the market.

Copper, nickel, cobalt, gold, silver, lead, zinc, molybdenum, and platinum.The environmental impacts of large-scale mining projects involving these metal ores are the subject of this guidebook.The guidebook does not discuss the mining of ores that are extracted using strip mining methods, including aluminum bauxite, phosphate, and uranium.
Despite being a non-metal, hydrogen is often included in the reactivity series since it helps compare the reactivities of the metals.The metals placed above hydrogen in the series can displace it from acids such as hcl and h 2 so 4 since they are more reactive.Important uses of reactivity series.

2 in concentrating copper ores, for example, pine oil is often used.The pine oil binds to the copper compounds, but not to the unwanted rocky material.The treated ore is then put in a large bath of water containing a foaming agent a soap or detergent of some kind, and air is blown through the mixture to make a lot of bubbles.
Nickel, copper, and iron ores are typically formed from magmatic or volcanic-related deposits.Carbonate alkaline ores are formed from other igneous processes other than volcanic and activity.

Typical examples of alloys are steel consist of the metal iron and the non metal carbon, stainless steel which is a combination of iron, chromium and nickel , solder a type of alloy whose melting point is lower than that of metal workpieces and so makes it to be used in joining pieces of metal works together , bronze composed of the.
