REMOVAL OF SULFUR AND PHOSPHOROUS FROM IRON

2016-5-17  The current study is focused on controlling sulfur emissions by pre-treating the iron ore concentrate to remove sulfur by leaching technique. Technically, chemicals are used to react with the sulfur bearing minerals in the iron ore to convert them into a soluble fraction, resulting in an easy separation from the insoluble solid phase. Since the amount of the iron ore concentrates, which must

Copper Mining and Extraction Sulfide Ores

From the formula, it is clear that iron and sulfur have to be removed in order to produce copper. The roasting process: changes some of the CuFeS 2 to copper oxide; removes some of the sulfur as sulfur dioxide; This is done by heating the concentrated ore from

Extraction of copper from an oxidized (lateritic) ore

2014-4-1  Sulfur was provided as the electron donor for the bacteria, and ferric iron present in goethite (the major ferric iron mineral present in the ore) acted as electron acceptor. Significantly more copper was leached by bacterially catalysed reductive dissolution of the laterite than in aerobic cultures or in sterile anoxic reactors, with up to 78 % of the copper present in the ore being extracted.

Sulphur Refining of Gold Mineral Processing & Metallurgy

2016-3-23  A more speedy method of removing iron, copper, lead and base metals from bullion is to add sulphur to the molten metals. Although gold sulphides may be readily formed in the wet way, they are decomposed into gold and sulphur by merely heating them to a temperature below 300 deg. C.

Zhang and Muhammad (1989) used nitric acid to remove phosphorus from the iron ore of the Kiruna region, Sweden. A concentrate of sinter, moist, and without treatment was used. Chemical analysis showed the composition of 0.98% phosphorus (as P 2 O 5 22.25%) and 60.85% iron. Nitric acid was chosen due to the low reactivity of the acid with the

Iron slag is removed and often recycled back into the furnace. Sulfur dioxide is captured and converted into sulfuric acid. The converted copper, known as "blister copper," is recovered. The blister copper then undergoes "fire refining." Air and natural gas are blown through the copper to remove any remaining sulfur and oxygen.
