Turning Slag Slurry to Angels Ores

[Rick]

I hate setting up mining outposts, so I started playing around with the mineral sludge processing, when I realised, that I am missing out on a great deal of refining.

So my question is: What do I have to change to make the mineral sludge filtering spit out angels ore and not the vanilla one (I'm also playing with Bobs, if that changes anything).
I have no idea of Modding whatsoever, so very detailed advice would be appreciated.

find the recipes for the slag->ore process. copy and rename them. change the output to the desired ore(look up the name in the lang files). include the name of your recipes into the tech. done.
