China Magnesium Smelting Cost Rises Nearly 3% W/W as Coal, Semi-Coke Diverge, Losses Widen
[SMM Weekly Magnesium Cost Express] During the week of Nov 1–6, prices of raw materials and by-products diverged for primary magnesium smelting: rising coal prices pushed smelting costs higher, while semi-coke prices kept falling on weak downstream demand; the two moving in opposite directions aggravated losses on the semi-coke side. Although coal tar remained at high levels, its limited output could hardly offset losses on the main products. On the cost side, under the dual impact of higher raw material costs and shrinking by-product income, primary magnesium smelting costs rose by nearly 3 percentage points week-on-week. Despite a mild rebound, magnesium prices lacked sufficient upward momentum, and losses of primary magnesium smelters widened further.
