This sand extraction will affect the local fish stock as well as white bait spawning, crabs and all other sea creatures that thrive in the waters and sand banks, tributaries, mangroves and swamps of the Sigatoka river. If we do not stop this mining operation now, it will destroy our environment for all future generations.
First, wash off the powder and impurities with water, and then use soak in acid, then rinse again with water, and finally dry or air dry. The above is the silica sand extraction process.
It is in the blast furnace that extraction of iron occurs. The extraction of iron from its ore is a long and subdued process, that helps in separating the useful components from the waste materials such as slag. What happens in the Blast Furnace? The purpose of a Blast Furnace is to reduce the concentrated ore chemically to its liquid metal state.
· Extraction. Extraction of Iron is done in many steps like oxidation, combustion, fusion, reduction, etc. During extraction cast iron is formed first which is then converted to wrought iron. Hematite is the ore that is used for extraction of cast iron. The ore is crushed into small pieces and is washed with water to remove the sand particles.

Iron Sand Extraction Process Sand mining presents opportunities to extract rutile, ilmenite and zircon, which contain the industrially useful elements titanium and zirconium. These minerals typically are found in ordinary sand deposits and are separated by water elutriation.
Sand and gravel deposits found on beaches or in rivers and streams, are mostly quartz (silicon dioxide, SiO2) grains. Weathering of rocks such as granite forms these quartz grains. In the process of weathering, the softer, weaker minerals in granite (such as feldspar) are weathered away.
· Concentration of Ore. The extraction of iron begins with concentration through calcination which is a process in a limited supply of oxygen applied to ores to bring thermal decomposition. An ore of a metal is an impure source. It consists of many impurities other than metal such as sand, clay, etc.
· Though iron pyrites (FeS 2) is also common ore of iron, but because of its higher sulphur content, it is not used for the production of iron. Extraction of Iron The cast iron is usually extracted from its oxide ore (haematite). This process involves the following steps:
· Produces molten iron. Fe 2 O 3 (s) + 3CO (g) 2Fe ( l) + 3CO 2 (g) The first reaction requires oxygen and we supply it by blasting hot air into the furnace. That''s why we call it the blast furnace. 3. Blasting our climate: carbon dioxide is the main by-product of iron extraction.
Iron, when extracted from iron ore such as haematite containing iron (III) oxide, Fe2O3, in a blast furnace is called iron extraction blast furnace metallurgy. In this reduction reaction, oxygen is removed from the iron (III) oxide to leave behind iron. Generally, the extraction of metals and their isolation are based on three major procedures.

· The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron (III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced ...

Case Study - South Taranaki Bight iron sand extraction. Iron sands are the largest known reserve of metalliferous ore in New Zealand. Iron sand is a general term for sand-sized grains of heavy iron-rich minerals, principally magnetite (Fe3O4), titanomagnetite (Fe2TiO3), and ilmenite (FeTiO3). New Zealand''s iron sands occur extensively in ...

The European iron workers knew the Easterners had better iron, but not the processes involved in fashioning stronger iron products. Entire nations launched efforts to discover the process. The first known European breakthrough in the production of cast iron, which led quickly to the first practical steel, did not come until 1740.
