Will Car Battery acid Be Sufficient to Clean Sulphides fast?

I have great material and I'm wondering if I use an old car battery (for acid), would this clean off all my sulphides,oxids, etc. I want a stronger acid than vinegar, tarn-x etc. Anyone have any easy ideas I can throw together from the grocery store?

I would not recommend using old battery acid. If you want sulfuric acid, get new clean battery acid from a store. Also, stay away from the sulfuric acid drain cleaners, they have dyes and thickeners in them.

I have three sources I use for my primary acids:

Nitric Acid 70% - Duda Diesel has by far the cheapest nitric acid if you buy 10L at a time.

Hydrochloric Acid 30% - Lowes or Home Depot sell this as Muriatic Acid. $10 a gallon

Sulfuric Acid 30-43%- Autozone sells it for ~$10 per 32 fluid ounces

Don't forget to pick up a few boxes of Baking Soda (Sodium Bicarbonate) for safety.

**updated with the URL for the non-green Hydrochloric Acid

I will also recommend NOT using the "green" HCl... it contains buffers that can affect in a negative way your processing!
Use their plain muriatic acid.

Take care!

Phil,

Thanks for the catch, I thought I had linked the regular hydrochloric acid and not the "green". I've updated the URL in the previous post.

Can you describe the material you have? Unless it is ore, why would sulfides be a problem? By letting us know what your primary material is, we may be able to help you determine which acid is best.
