384 Miscellanies. 



ore is sorted from the copperas ore, by men with hammers — the 

 copper ore appears to be in abundance, yet it bears but a small pro- 

 portion to the copperas ore with which it is connected ; after being 

 sorted from the copperas ore, it is piled in heaps of from eighty to 

 one hundred tons on a layer of wood and charcoal ; the wood and 

 coal are then set on fire, and .owing .to the sulphur contained in the 

 ore, the whole becomes readily ignited, and in this manner it is al- 

 lowed to roast for about one month. It is then taken to the smelting 

 furnaces, of which they have two in operation, and are building two 

 more, the whole about one mile from the mine. Here the ore passes 

 through three operations of smelting — the first does not produce any 

 copper; what runs out of the furnace is broken up and passes through a 

 second process of roasting, and is again smelted, which produces some 

 copper — the slag is again broken up and roasted as before — the third 

 operation of smelting obtains all the copper except about half per 

 cent, which remains in the slag, and this slag is thrown away. The 

 ore has yielded thus far about ten per cent. The fuel is charcoal.
