This scheme use 240/s raw common tungsten ore (need 1 full belt), about 150/s common coal, sulfuric acid and magma. And all this gives about 150/m legendary tungsten carbide! Also its use sulfiric acid, magma and small amount of calcite. For work need about 50-100 legendary logistic bots. (Steel productivity 300% here must be)
Coution! Legendary foundry carried by bots, so bots network must be separate from your main base, or they will burn all of your legendary foundries.....
P.S. Best to use it together with similar modules, for more effect, because this scheme can consume only 1 full belt of tungsten ore.
P.S.S. give me like!
