Show THE HANCOCK JIG era clifton ariz for some month past the arizona copper company has ben experimenting with the hancock jig the only one of the kind ever introduced in america the results have been satisfactory beyond expectations and the company is now manufacturing another machine which will be placed in the first vanner room and is expected to take the place of thirty three banners van ners the two machines will then handle tons of ore per day at a greatly reduced cost over the old methods of treating the ore the jig which Is now being constructed will occupy only as much space as two or of the van ners and can be operated op eksted for a very small expense and seldom needs repairing archie morrison superintendent of the concentrator cen is more than well pleased pleas e d with the machine which is already in use but cannot tell until after the new machine is in operation whether it will successfully handle bandle the ore that is reground by the hunt ing tons but he is s quite confident that it will prove a success it would seem that these machines are destined to play an important part in reducing the cost of mining in the southwest they agrenot are not expensive require no building to speak of and at the same time they can be run with a very small amount of water in comparison with other machines which handle the same amount of ore in a day if the new machine works as successfully on fine ground ore as the other machine works on coarse ore it is quite evident that two per cent ore can be handled at a profit in this district the machine has ben inspected by mining men from all parts of arizona and mexico and it has proved a wonder to them |
