It was a week of upward momentum for the S&P/TSX Venture Composite Index (INDEXTSI:JX), which started the period at 917.91 and ended at 947.08. Gold was also on the rise during the five day period Manganese Industry: Supply and Demand. As mentioned, the steel sector accounts for most manganese demand. In all, the industry consumes 85 to 90 percent of manganese, using it as a deoxidizing and desulfurizing additive and as an alloying constituent. Among other things, manganese can improve the strength, toughness and stiffness of steel.
