Selective Flotation - Mineral Processing & …
Who would think that Selective Flotation of copper, gold, zinc or any metal would required that one must be able to feel pain and recognized and/or admit when it hurts. Flotation mass-pull is a process that is often misunderstood; a learner’s mistake made by non-operating types. You do not need to pump anything in the lab. In selective flotation, less is more! Over 2 years ago I wrote about ...

MEI Blog: Challenges in copper flotation - Barry A. …
17.09.2011 · Arsenic-bearing sulfide minerals like tennantite are difficult to separate from other non-arsenic sulphide copperminerals in conventional copper flotation circuits. The most successful approaches to effecting separation appear to be based on selective oxidation techniques and the use of pulp potential. The situation can be more complex if the ore body has enargite, which is an arsenic …

Which flotation scheme used in the differential copper-lead bulk concentrate separation is generally and often dependent upon which mineral has the greater mass in the bulk concentrate. Whichever mineral constitutes the lower bulk concentrate mass will be floated away from the other mineral which is depressed for flotation selectivity reasons ...
Arsenical bronze - Wikipedia
Arsenical bronze is an alloy in which arsenic, as opposed to or in addition to tin or other constituent metals, is added to copper to make bronze.The use of arsenic with copper, either as the secondary constituent or with another component such as tin, results in a stronger final product and better casting behavior.. Copper ore is often naturally contaminated with arsenic; hence, the term ...
