Answers | Yahoo Answers

Best answer: One main reason is that reduction from ores by electrolysis is comparatively expensive when there are cheaper coal-based reducing agents (i.e. coke) are available. Such thermochemical processes are also more readily implemented at a large scale (blast furnaces) than is electrolysis, which necessitates a lot of readily available ...
