How much electricity does high-carbon ferromanganese production use per ton?

Created from Britannica articles using AI. AI can make mistakes, so verify using Britannica articles.

The electricity consumption for producing high-carbon ferromanganese depends on the specific smelting method employed:

Method 1: This process, which recovers 70 to 80 percent of the manganese, consumes 2,400 to 2,800 kilowatt-hours of electric power per ton of product.1
Method 2: This process, which utilizes basic ores or fluxes to achieve a higher metal recovery of 85 to 90 percent, requires more energy to calcine the fluxes and consumes 2,600 to 3,100 kilowatt-hours per ton.1
