Metals

The backbone of your Mining operations will be determined by your skills in supplying yourself with enough materials, to craft mining machines or any other materials you might need.

Forging
The process for making metals differ, but the process of crafting them remains the same. You can use your Induction Furnace to smelt all of the ingots and should you not have one yet, you can also use the Iron Forge and Coke Oven to melt them. Any metal or steel that uses more than one Ingredient can be smelted with your Induction Furnace or Iron Forge. Referring to the wiki on Ores all your ingots will either be melted or crushed, the 3rd and last phase of mining (Phases being crush, pan, smelt/crush again)

From here on using the Machine Press or Iron Work Bench Adv or Iron Press you will process the ores into usable metals. The Machine Press has a multi input slot for merging multiple metals together and the Iron Press has the same multi input, but works manually and in some cases will yield less.

Steel Works
In most cases the sheets you just crafted can be turned into rods, usable in a variety of machine recipes.

Metals crafted from multiple sheets or metals, can only be crafted using the Iron Press or the Machine Press.

Multi Induction
Multi Induction is a mere process we refer to us combining different ingots to form a completely new ingot that's not normally obtainable thru world generation

To merge ingots, you can use your Induction Furnace and should you not have one yet you can always use your Coke Oven, again the yield will be less using the Coke Oven.
