1 The influence of sodium silicate on the ability of a diacetylene-containing phospholipid (23:2 diyne PC) to inhibit the oxidation of pyrite at pH 2 and pH 6 was investigated. pyrite polyhomeotic homolog 2 Homo sapiens
2 The lipid is superior to the silicate in suppressing pyrite oxidation at both pH 2 and pH 6. pyrite polyhomeotic homolog 2 Homo sapiens
3 Also, the presence of silicates decreased the ability for the lipid to suppress pyrite oxidation, both at pH 2 and pH 6. pyrite polyhomeotic homolog 2 Homo sapiens
4 The reaction mechanism for pyrite oxidation at pH 2 is first order for pyrite leached by solutions containing only ferric, ferric together with silicate, and ferric combined with silicate and lipid. pyrite polyhomeotic homolog 2 Homo sapiens
5 The reaction mechanism for pyrite oxidation at pH 2 is first order for pyrite leached by solutions containing only ferric, ferric together with silicate, and ferric combined with silicate and lipid. pyrite polyhomeotic homolog 2 Homo sapiens
