Show THE JOSEPH LEACHING PROCESS T B joseph of mercur is the inventor and patentee of a new leaching process which is attracting the attention of mine owners and fillmen at the present time one feature of the process so it is claimed being that it will reduce base low grade gold ores without previous roasting as successfully as the cyanide process is now being employed in the treatment of oxidized and roasted base ores while it is claimed that the joseph method is cheaper and the chemicals used are not as costly as those utilized in the employment of the cyanide process in a letter to the mining review mr joseph in commenting 0 on his process states that he has repeatedly tested it on free milling gold ores the headings assaying 25 to the ton with an extraction of 99 per cent of values while on oxidized oxidize dores ores carrying 3 to the ton in the yellow metal a 93 per cent saving has been recorded on the most rebellious bel lious black ores from the daisy mine on the west dip an extraction of 91 per cent has been made base ores from the sacramento the headings showing values of being treated with a recovery of 75 per cent it being mr josephs belief that with a stronger solution a still greater saving would have been made mr joseph feels confident that his process will extract more gold g old from base and oxidized ores than any other leaching process now in existence as it can be used on these classes separately or they can be treated together mr joseph promises to keep the review posted upon the success attending the numerous experiments being made by him with his new process |
