Iron ore production flow chart . iron ore production flow chart. the manufacture of steel, iron occurs mainly as oxide ores, though it is also found in smaller quantities as its sulfide reduced with carbon from coal, through the intermediate production of carbon monoxide. the flow diagram for this process is shown in figure 1.material flow in.
A flowchart is a picture of the separate steps of a process in sequential order. It is a generic tool that can be adapted for a wide variety of purposes, and can be used to describe various processes, such as a manufacturing process, an administrative or service process, or a project plan.
Step 1 – The iron making process. As iron is the main component of steel it firstly needs to be made. Iron ore, lime, and coke are placed into a blast furnace and melted. The resulting liquid known as molten iron is then formed. As molten iron still contains around 4% – 4.5% impurities such as carbon which in turn make the metal brittle ...

They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron. The stock level is constantly 'topped up'. Molten iron ore is 'tapped' at the bottom of the blast furnace, poured into the iron ladle and removed for …
and casting abilities of ductile cast iron makes it economical choice for many applications. Practical examples are valves, pumps, cylinder liners, crankshafts, metal working rolls, dies, gears, process equipment and structural applications. This paper reviews the process techniques and applications of ductile cast irons.

A flowchart is a visual representation of the sequence of steps and decisions needed to perform a process. Each step in the sequence is noted within a diagram shape. Steps are linked by connecting lines and directional arrows. This allows anyone to view the flowchart and logically follow the process from beginning to end.
The process flow is relatively simple. If the crystal grain size is too fine, the process of stage grinding, stage magnetic separation and fine sieve regrind is adopted. This process is the third stage of grinding and fine grinding after the products on the first and second stages of fine sieve are concentrated and magnetically separated.

• Molten material can flow into very small sections so that intricate shapes can be made by this process. As a result, many other operations, such as machining, forging, and welding, can be minimized. • Possible to cast practically any material: ferrous or non-ferrous. • The necessary tools required for casting moulds are very simple and
Step 1 - The production of molten iron The Primary Concentrate is mixed with limestone and coal and heated. The iron oxides are reduced in the solid state to metallic iron, which then melts, and the impurities are removed either as slag or gas. The flow diagram for this process is shown in Figure 1. slag electric melter CO2 and waste gases CO ...
