High coking coal prices provide glimpse into steelmaking's …
Higher-priced coking coal is likely to affect the steel industry's transition to greener production methods as well as the value-based pricing of iron ore. Higher-priced coking coal increases the cost of producing steel via blast furnaces, both in absolute terms and relative to other routes. This typically leads to higher steel prices as raw ...
