INFCLLinkProducts: Quick Launch
An ore is an occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit.

Tin is one of the basic chemical elements. When refined, it is a silvery-white metal known for its resistance to corrosion and its ability to coat other metals.
Australia's iron ore reserves and resources are in both hematite and magnetite ores. Because of the high average grades (% Fe) of hematite ores when compared to the average grades for magnetite ores, it is necessary to report national resources in terms of contained iron.
Froth flotation is considered to be the most widely used method for ore beneficiation. In ore beneficiation, flotation is a process in which valuable minerals are separated from worthless material or other valuable minerals by inducing them to gather in and on the surface of a froth layer.
The process of extracting copper from copper ore varies according to the type of ore and the desired purity of the final product. Each process consists of several steps in which unwanted materials are physically or chemically removed, and the concentration of copper is progressively increased.
Copper processing: Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products.

Aluminum is a silver-white metal and is very light in weight (less than three times as dense as water) yet strong. Because aluminum is ductile, it can be drawn into wires or pressed into sheets or foil.
Silver is a chemical element with symbol Ag (from the Latin argentum, derived from the Proto-Indo-European h₂erǵ: "shiny" or "white") and atomic number 47. A soft, white, lustrous transition metal, it exhibits the highest electrical conductivity, thermal conductivity, and reflectivity of any metal.
Lead processing: Lead processing, preparation of the ore for use in various products. Lead (Pb) is one of the oldest metals known, being one of seven metals used in the ancient world (the others are gold, silver, copper, iron, tin, and mercury).
Asian Journal of Science and Technology (AJST) is a monthly, open access, peer-reviewed and fully refereed international journal. Being an international journal focused on Engineering, Management, Science and Mathematics, we broadly cover research work on next generation cutting edge technologies and effective marketing strategies.
Only six of the top 20 producers are primary silver miners. The polymetallic ore deposits from which silver are recovered account for more than two-thirds of the world's silver resources.
Iron Ore Agglomeration Processes and their Historical Development. There are four types of agglomerating processes which have been developed (Fig 1).
The general focus of this document will be on metaliferrous ores represented by run-of-mine material described in category 3 above. An exception to the above discussion of mineral processing arises when the valuable component of the ore is extracted directly by chemical methods.
