I have been building furnaces for melting various metals like Aluminium, Copper and its Alloys and Cast iron(small scale hit or miss). I'll like to build a Cupola furnace specially for melting cast iron and I will need some high quality Coke.
1. Where can I get some Coke on retail scale in Nigeria?
2. Where can I get FerroSilicon on a retail scale in Nigeria?


Note: My furnaces are for hobby uses therefor not big scale.
