The Lower-grade sources of iron ore generally require beneficiation, using techniques like crushing, milling, gravity or heavy media separation, screening, and silica froth flotation to improve the concentration of the ore and remove impurities.
copper extraction and purification - chemguide
This page looks at the extraction of copper from its ores, its purification by electrolysis, and some of its uses. Before you get too bogged down in the extraction of copper, make sure that you need it for whatever syllabus you are using.
Iron processing |
Iron processing: 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.
Eco Line Serie by Silestone
Life- Cycle Analysis (LCA) is a pioneering tool within the area of sustainable politics and actions. It investigates and evaluates the environmental impacts of a product or service during all stages of its existence (extraction, production, distribution, use and waste).
Gold extraction - Wikipedia
Gold extraction refers to the processes required to extract gold from its ores.This may require a combination of comminution, mineral processing, hydrometallurgical, and pyrometallurgical processes to be performed on the ore.
Our Wabush 3 Project - Iron Ore Company of Canada
Current situation. IOC has been operating the Carol Project in Labrador City since the 1960s. The Labrador City Operation produces concentrated iron ore and pellets (further processed), and transports these by train to the port of Sept-Îles on the Gulf of St. Lawrence and from there to global customers.
EXTRACTION OF IRON- EXTRACTION OF IRON FROM HAEMATITE

IRON AND STEEL - chemguide
This page looks at the use of the Blast Furnace in the extraction of iron from iron ore, and the conversion of the raw iron from the furnace into various kinds of steel.
Iron ore pellets - an overview | ScienceDirect Topics
Iron Ore Induration. The term induration describes the hardening of a powdery substance. For example, in steel production, iron ore pellets are fed into melt furnaces. To avoid dusting and loss of ore, small oxide particles are agglomerated by sintering.
How iron is made - material, manufacture, making, history ...
then reacts with the iron ore to form carbon dioxide and pure iron. Separating the iron from the slag 2 The melted iron sinks to the bottom of the furnace.
GCSE CHEMISTRY - Extraction of Iron - GCSE SCIENCE
Extraction of Metals. Extraction of Iron.. Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide).
