Talk:Phosphate rock

From Wikipedia, the free encyclopedia

I have created entry for phosphate rock , distinct from phosphate minerals. Discussion of rock ( assemblages of minerals ) is somewhat distinguished from the discussion of individual mineral compounds ( i.e. quartz, mica, feldspars are minerals, granite and sandstone are rocks ). We will be adding information about economic ores which are mined for their phosphate mineral content.Eregli bob (talk) 12:12, 17 March 2008 (UTC)
