usefulness it will be interesting to know something of the plants characteristics and the methods methoW that hat are to be employed in recovering the he copper from the ore The mill build buildIngs buildings buildIngs Ings are constructed entirely of steel The crude ore Is received in a main bin over which the railroad trains travel and which has a capacity of tons From this main bin the ore Is taken by con conveyor conveyor conveyor belts to the crushing plant which Is equipped with four Gates rotary crush crushers ers From the crushing plant the ore Is Isaken taken aken by b slightly inclined conveyors to the top of the thc main mill bins which have a capacity equal to that of the tho receiving bins There It is distributed by a trip tripper tripper tripper per belt the entire length of the bins Crushing of the ore in the mill Is ac accomplished accomplished accomplished by Nissen Nisen NI en individual stamps arranged in double dobie rows longi longitudinally with the bin These stamps are fed ed automatically and crush to h Pulp is passed to the classifiers where It t separates into three divisions passing thence hence to the he various machines for the recovery of the product which Include tables 2 S Johnston tables and Callow settling tanks Settling ca capacity of the plant Is unusually large All the he clean water from the settling tanks passes asses to a sump which sends it back to the main supply A distinguishing feature of the Boston Consolidated mill Is that there theres is s not an nh elevator In the tho entire plant Everything passes by gravitation through the works The daily dally capacity will run from LOGO to tons The company compan has no investment in pow power er plant as it has secured a very verv fa favorable favorable a rate from the
