Iron Manufacturing process related to the specified
Iron powder via electrolysis . The manufacture of iron powder by electrolysis is a batch process. The anodes are usually made of iron or low carbon steel. The electrolyte of the cell consists of a sulphate solution (temperature 50°C). Pure iron is deposited as a brittle lightly adhering sheet on the cathodes. After washing, drying, and

Preparation Methods of Metal Powder Industry
Industrially, the hydroxyl method is mainly used to produce fine powders and ultrafine powders of nickel and iron, and alloy powders such as Fe-Ni, Fe-Co, and Ni-Co. The powder obtained by the hydroxyl method is very fine and has high purity, but the cost is also high. *

How Metal Powder Is Made: Step 1 of the Powder
Iron or other ferrous metals are often popular in powder metallurgy because of their magnetic qualities. 2. Make the metal powder. There are four main methods of making metal powder. Which method is used depends on an abundance of factors -- particularly the type of metal that needs to be powdered and the properties you’re prioritizing.

Direct reduced iron Wikipedia
Process. Direct reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of iron ore (sized ore, concentrates, pellets, mill scale, furnace dust, etc.), in order to convert the ore to metallic iron, without melting it (below 1,200 °C (2,190 °F)).
