Ore Concentrate is defined as Ore that has been treated so that the solid materials are reduced in size, by crushing, grinding and/or other process with the gangue ( waste) being removed, thus concentrating the metal component. For the purposes of this agreement, one ton of Ore Concentrate is equal to ten tons of Ore.
Concentrate: ore that has been refined to remove the bulk of waste materials. Handling iron ore in bulk carrier Most iron ore is carried in Cape-size ships, i.e. larger than 80,000 tonnes deadweight, although ships of this category are often much bigger and are generally in the region of 170,000 tonnes deadweight.

Platts Iron Ore Index, or IODEX (IODBZ00), is a benchmark assessment by S&P Global Commodity Insights of the spot price of physical iron ore. The assessment is based on a standard specification of iron ore fines with 62% iron, 2.25% alumina, 4% silica and 0.09% phosphorus, among other gangue elements.
Iron Concentrate is created by purifying Crushed Iron Ore. This can be done in one of two ways: either dry or wet purification, each of which can be performed using one of two crafting stations. The crafting stations come with different ratios, labor cost and time.

Iron concentrate is similar to powder in that it is made up of minute, dry particles of pure substance. Concentrate is also useful in any application where high surface areas are desired such as water treatment and in fuel cell and solar applications. Nanoparticles also produce very high surface areas.
iron ore concentrates means products resulting from the concentration or other beneficiation of iron ore, other than by crushing or screening, and includes thermal electrostatic magnetic and gravity processing, but excludes the production of iron or steel, metallised agglomeration, …
The iron ore pelletizing process consists of three main steps: Pelletizing feed preparation and mixing: the raw material (iron ore concentrate, additives—anthracite, dolomite—and binders are prepared in terms of particle …
Concentration refers to the methods of producing ore fractions richer in iron and lower in silica than the original material. Most processes rely on density differences to separate light minerals from heavier ones, so the ore is crushed and ground to release the ore minerals from the gangue. Magnetic techniques also are used.
The following Iron Ore specifications guide contains the primary specifications and methodologies for Platts Iron Ore assessments throughout the world.

Tin concentrate is smelted to resmelted slag for additional tin recovery. The furnace charge consists of tin ore (cassiterite), a carbon reducing agent (coke), and limestone and silica fluxes. The quantity of coke and flux is carefully adjusted so as to produce an almost neutral slag (ie, acid-to-base ratio is 1). The smelting takes 10–12 h.
Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3 ). Iron ore is the source of primary iron for the world's iron and steel industries.
