Flotation separation of copper–molybdenum sulfides using

The yield of molybdenum-bearing copper concentrate was too low in each batch flotation to carry out the copper–molybdenum separation because of the low grade (0.90% Cu and 0.056% Mo) of the ore. Therefore, the molybdenum-bearing copper concentrates from different batches were blended together to obtain sufficient sample for copper

Copper-Molybdenum ores Danafloat

Recovery of copper is by standard flotation reagents identified in the copper ore flotation description. Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability.

Reducing Excess Copper with Molybdenum FX Medicine

Molybdenum has been shown to reduce copper levels by increasing the amount excreted in urine and interfering with gastrointestinal absorption.[] In the gastrointestinal lumen, molybdenum forms insoluble complexes (copper molybdate and copper thiomolybdates) with copper thus preventing its absorption and incorporation into plasma proteins such as ceruloplasmin and other copper-containing proteins.

Brazing Wikipedia

Brazing is a metal-joining process in which two or more metal items are joined together by melting and flowing a filler metal into the joint, the filler metal having a lower melting point than the adjoining metal.. Brazing differs from welding in that it does not involve melting the work pieces and from soldering in using higher temperatures for a similar process, while also requiring much
