20/07/2005 · LeadZinc. The leadzinc ore deposits and indiions in Iran number more than 600. Taking into account the average grade of the ores, the amount of lead and zinc metals is estimated at 18 and 5 million tons, respectively. There is a high probability of finding new large reserves as the exploration techniques advance. (See Table 20, Table 21.)

At around the same time, it was realised that the mineral sphalerite (zinc sulphide) could also be used for the same purposes, and new techniques for making brass directly from zinc were patented. By 1779, Bristol brass was in great demand, and Shipham and Rowberrrow became the centre of the zinc mining .
