Roasting?[edit]

Is roasting considered to be a beneficiation process, or something else? I'm thinking particularly of spathic iron ore, carbonates, which are roasted before smelting to drive off CO₂ Andy Dingley (talk) 11:31, 16 July 2015 (UTC)[reply]

Smelting is the process for that and would follow physical separation processes. Vsmith (talk) 02:18, 22 July 2015 (UTC)[reply]

No, smelting is definitely not the process. This is a simple heating, not a specifically reducing atmosphere to produce metallic iron. Maybe there should be an article on spathic iron ores that might explain the problem? Andy Dingley (talk) 02:35, 22 July 2015 (UTC)[reply]

See Smelting#Roasting. Vsmith (talk) 03:47, 22 July 2015 (UTC)[reply]

Yes, that's the process. Is it considered as a form of beneficiation? Andy Dingley (talk) 09:31, 22 July 2015 (UTC)[reply]

I've no expertise here, but beneficiation involves physical separation of ore from gangue - whereas roasting involves a chemical change of the ore mineral to an oxide or other form more easily processed to a metallic form. Vsmith (talk) 01:22, 23 July 2015 (UTC)[reply]

So what's the definition of beneficiation then? "Separating an ore stream into two: one more valuable and one less valuable" would have a nice sense of unambiguous definition and consistency about it. Except that the South African source already listed is far broader, and specifically includes smelting. So is beneficiation anything that "increases the value" of a mined product? Andy Dingley (talk) 01:28, 23 July 2015 (UTC)[reply]

The South African reference seems much more inclusive than others. The US EPA document states: "Beneficiation," defined by 40 Code of Federal Regulations (CFR) 261.4, means the following as applied to iron ore: milling (crushing and grinding); washing; filtration; sorting; sizing; gravity concentration; magnetic separation; flotation; and agglomeration (pelletizing, sintering, briquetting, or nodulizing). (source: Link from google search for beneficiation ore: U.S. EPA 1994, Extraction and Beneficiation of Ores PDF) (Hmm... Wikipedia blocks the link?) Vsmith (talk) 02:06, 23 July 2015 (UTC)[reply]

Content merged[edit]

Merged content from Benefication (metallurgy) an alternate spelling. Vsmith (talk) 02:05, 22 July 2015 (UTC)[reply]

Any proof that this is a valid alternative spelling? It is not in the OED, either as "benefication" or "to beneficate". Websites using it tend to use "beneficiation" later on in same article. Looks more like a common misspelling. — Preceding unsigned comment added by 2003:C4:A3DD:E501:1C21:BAB:6C0D:2C8F (talk) 11:27, 14 September 2017 (UTC)[reply]
