iron ore ratio to hot metal
Iron ore 62%-65% Fe spread expected at over $20/dmt in
Chinese steelmakers exhibited an increasing preference for iron ore with higher iron content and lower silica and alumina levels, for furnaces to produce less slag and more hot metal per ratio of Direct Reduced Iron , Industrial Efficiency Technology ,Direct Reduced Iron (DRI), also known as Sponge Iron, offers an alternative steel production route to BF-BOF and Scrap-EAF routes. In DRI, iron ore is reduced in its solid state – unlike BF process where a liquid metal is formed during reduction.
Pig iron Wikipedia
Pig iron is an intermediate product of the iron industry, also known as crude iron, which is first obtained from a smelting furnace in the form of oblong blocks. Pig iron has a very high carbon content, typically 3.8–4.7%,  along with silica and other constituents of dross, which makes it very brittle and not useful directly as a material except for limited applications.PRODUCT GUIDE the ICE,More directly, relational pricing can exist between iron ore and steel (known as the "metal spread") and iron lump to steel (the "hot metal spread"). These 'lumps' are the intermediate stage between iron ore and pig iron.

Iron ore Wikipedia
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.Creating Iron , HowStuffWorks,Once it cools, this metal is known as pig iron. To create a ton of pig iron, you start with 2 tons (1.8 metric tons) of ore, 1 ton of coke (0.9 metric tons) and a half ton (0.45 metric tons) of limestone. The

It is a two-stage process which has been developed in Japan. It uses non-coking coal in a powder or granular form to smelt iron ore fines into liquid iron (hot metal) and hence, there is no necessity of a coke ovens plant and a sintering plant. The ore fines are pre-reduced in

The refining of iron to make steel is where the carbon content of hot metal is lowered usually to less than 1 % by an oxidation process in a steelmaking furnace At the same ime alloying t At the same ime alloying tIron ore quality differentials evolve as market ,In simple terms, the higher the slag volume per mt of hot metal, the higher the rate of coke consumption and reductant costs. A general rule of thumb in furnace chemistry is that for every +0.1% Si increase in hot metal, the coke rate increases by +6.5kg per mt. So we believe the silica penalty should in part be a reflection of metallurgical coal and coke prices, which directly affect the cost

It is widely distributed, combined withFrom ore to steel – ArcelorMittal,Fine-grained iron ore is processed into coarse-grained clumps for use in the blast furnace. Coal is cleaned of impurities in a coke furnace, yielding an almost pure form of carbon. A mixture of iron ore and coal is then heated in a blast furnace to produce molten iron, or pig iron, from which steel is made.
