CN101234363B - Method for producing high …
The invention relates to a method to produce high grade sulfur concentrate by using low grade pyrite ore, which takes pyrite ore containing 8 percent to 25 percent sulfur as raw material which is smashed and milling ground to allow the pyrite ore to be dissociated from rocky mineral monomer. Ore slurry is arranged on spiral chute to obtain rough concentrate with the sulfur containing grade ...
Operation on Low-Sulphur Fuels
Low-sulphur heavy fuel has a some-what higher price than the high sulphur heavy fuel, due to increasing demand and the cost of the desulphurisation process. When switching from heavy fuel to a distillate fuel with a low aromatic hy-drocarbon content, there is a risk of incompatibility between the two prod-ucts. The change-over procedure takes
Sulphur in Steels
For this reason, S is kept as low as 0.005 % or less in these steel products, particularly when they are used for such critical applications as arctic grade line pipe and ship plate. Mention is however being made, of what has been called the ‘sulfur paradox’ in high strength low alloy (HSLA) steels. Increasing the S content from a nominal, say 0.008 % to 0.060 % lowers the Charpy upper shelf level, thereby …
Gray Iron
Consequently, for most applications the optimum operating level for manganese appears to be about (1.7 x % Sulfur), + 0.3% to 0.5%. For example, for an iron with 0.10% Sulfur, the optimum range for Manganese would be 0.47% to 0.67%. Running toward the low end of the range would normally maintain higher hardness and tensile strength while running toward the high end would decrease …

Pig iron
Some pig iron grades are suitable for producing ductile iron. These are high purity pig irons and depending on the grade of ductile iron being produced these pig irons may be low in the elements silicon, manganese, sulfur and phosphorus. These types of pig iron are used to dilute all the elements (except carbon) in a ductile iron charge which may be harmful to the ductile iron process. Modern uses
