产生铁的

"This is not always true--as with the manufacture of pig iron and steel from low-grade iron ores -- but it did lead to the concentration of industrial developments on the coalfields, a phenomenon well seen in such countries as Britain where the Industrial Revolution came before the days of oil or electricity."

也不总是这样(例如用低品位铁矿石冶炼生铁和钢)，但这种情况的确导致了工业发展集中在产煤区，这一现象在工业革命发生于石油或电力时代之前的英国之类的国家里特别明显。

Shanxi was an important province of north China which largely produced iron in Song, Yuan, Ming, Qing dynasty. There were a lot of places to exploit iron ore, and exploitation scale was increasing. The technique of smelting iron was generally improved and pig iron outputs increased. All kinds of handworked ironworks not only satisfied the production and living requirement of this province, but also were sold to other provinces, even abroad. Smelting iron industry became an important handicraft industry of this province, which directly promoted the economical development of Shanxi.

宋元明清时期，山西是北方重要的产铁大省，铁矿开采点多，开采规模扩大，冶铁技术得到普遍提高，生铁产量增加，各种手工铁制品不仅满足本省生产生活需求，而且远销其它省份甚至国外，铁冶业成为本省重要的手工业部门，直接推动着山西经济的发展。
