Galena is the ore from which elemental lead is extracted. In the first step of the extraction process, galena is heated in air to form lead (II) oxide. 2PbS (s) + 3O2 (g) → 2PbO (s) + 2SO2 (g) ΔH = – kJ What amount of heat (in kJ) is liberated if 224 g of Galena (PbS) is converted to lead oxide?

Get Price· 'Elsevier BV' Abstract The degree of oxidation during grinding and its effect on galena flotation were studied using a specialised mill which permitted chemical conditions during grinding to be controlled. It was found that iron oxidation species derived from the grinding medium played a dominant role in galena flotation.
Get PriceGalena Lead Ore Beneficiation and Upgrading Plant. The composition of galena is PbS with its good floatability and specific gravity of So the beneficiation of galena lead ore is floatation separation and gravity separation. Floatation separation makes use of its floatability to get high grade galena

Get PriceFor galena lead ore with coarse granules embedded, crushing—gravity jigging can help to get ideal grade with low beneficiation cost and plant cost, and the most important one, better beneficiation efficiency than floatation separation.
Get PriceThe crude galena is crushed and screened to make the galena granules liberated from its gangue. Kind of gravity separators like jigging machine can be used to purify the galena to get galena concentrate and tailings. Machines like crushers, rod mills, jig separators, shaking tables can be involved in galena gravity processing flow sheet.
Get PriceThe invention discloses a flotation separation method for molybdenite and galena, which comprises the following steps of: 1, rough grinding; 2, rough selection and scavenging for obtaining leadcontaining molybdenum rough concentrate; 3, regrinding after a certain amount of active carbon is added into the leadcontaining molybdenum rough concentrate; and 4, .
