Mining Dangers Traditionally mines were operated on small scale focusing on coal near the service however as the demand increased as did the need to find more coal Mines therefore began to get deeper As they began to get deeper they were flooded with groundwater which made working conditions difficult The coal was cut by hand with a pick axe
The process works best when the ore is crushed to small pieces before roasting Additives such as common rock salt are often added to the mix before it is heated to enhance the reaction of the sulfides Once the ores are fully roasted and the sulfur is driven off the extraction of the gold or silver from the ore is not especially difficult
