Show NEW FLOTATION METHOD according to john F cowan a prominent salt lake mining man who recently returned from a trip to new york a new flotation reagent has been invented that is destined to work wonders in the treatment of low grade milling ores judged by the success of demonstrations witnessed by mr cowan the reagent is described as a chemical compound which does all that oil does in creat ing a froth and picking up the metals on the froth bubbles the value of the new reagent is in Us its low cost which is said to be much less than the cost of oil it has been found that a cleaner concentrate is also made by the new reagent as compared with concentrates made with an oil froth and that the froth can be broken down easier than oil froth clear water breaking it down rapidly oil flotation is only used in milling sulphide ores while some splendid results result shave have already been obtained in milling oxidized ore with the new reagent oxidized ore flotation has not as yet been as far developed as sulphide ore flotation mr cowan said but results already obtained give promise of developing the field of flotation to a marked degree with the use of the new dew chemical canadian rights for the use of the invention according 0 to information given mr ir cowan in new york were sold to a big canadian mining firm for after an extensive series of tests had been made with the new discovery at the toronto university laboratories tests made while mr cowan was present showed that the reagent c reates creates a froth equally as good as does oil it has the effect of cleaning the concentrate of a large part of iron pyrites and etite so that a higher grade concentrate is made some of 0 the tests showed that where oil flotation had bad been used in milling a copper ore the concentrate cen was brought to between 10 and 11 per cent copper while the concentrates from the same ore made with the new reagent reagen 14 and 15 per pe to between were brought up lip cent copper com co mining some of the largest copper panics in the country which are either bur by the t bened or threatened with litigation WM infringing minerals separation company for the new on the oil flotation rights are testing reagent mr cowan said it is probable proba blei that C a large part of the minerals separation will be banys hold on the flotation process the while wm broken by the new discovery e larg holds a minerals separation company by patents it is regarded number of flotation anven 0 on n two rely most people that they per of 0 one and use eions violent agitation the b bibble cent or less of oil for f frothing be 15 column towne and flynn process to lieveld by most mining people hold on the the minerals separation new ne cl if the tion feature of flotation holds up to the promise it indicates indica separation minerals every possibility that will lose its flotation monopoly nies g are conica colv A large number of mining cent oil now using more tharl than one per that belief making flotation froth in the e 1 6 evad evading n 1 alivera mine so doing they are is a vent new in the tion rights the e on not inan will vill cal compound which oil patent mr cowan said |
