Abstract
Metal displacement by ball milling process is used to displace metals with higher potential than zinc powder. The prior art cannot displace completely, usually in interrupted operation with low use ratio of raw material. This invention involves a milling cylinder as displacing container, in which displacing solution and metal balls are contained. Displacement is completely carried out by activated surfaces of metal balls when rotating the displacing cylinder. It has no specificity on acid degree of the displacing solution and can be used in metal purification or wastewater treatment. Iron can replace zinc when displacing some metals.
Description
The present invention relates to a kind of metal displaces other metal in solution method.
In solution, add the lower metal of electromotive series current potential, metal ion exchanged precipitating metal that can be higher with current potential.For example go out other metal with zinc dust precipitation.The shortcoming of this method is: raw material availability is low, and displacement not exclusively generally can not continuous production, and operation is trouble.
Purpose of the present invention: cut down the consumption of raw materials with fairly simple continuous production method, improve the metal replacement rate of recovery.
Content of the present invention: in the solution in ball grinding cylinder, add the metathetical Metal Ball, displace other metal.
Particular content of the present invention is provided by accompanying drawing.
The schematic flow sheet of accompanying drawing ball milling metal replacement method
Ball grinding cylinder [1] can single or multiplely be formed.Ball grinding cylinder turns forward slightly.Have in the ball grinding cylinder by metathetical solution [3] and Metal Ball [2], when ball grinding cylinder rotated, Metal Ball rubbed mutually, remove passive film and produce active face, it very easily with by the metathetical metal ion reacts, and the metal that displaces is attached to the ball surface, because friction comes off very soon, ball forms active face again.In addition, the Metal Ball self friction also has metal mill down, and this particulate activity is stronger, except that metal replacement, and can with by the metathetical melts combine, so the metal replacement rate of recovery is higher, be more suitable for the recovery of low levels metal in the solution.
Metallic particles [7] flows out with the solution [4] after replacing, precipitation when precipitation ramp pan [6].Top solution [5] flow to next ball grinding cylinder and proceeds metal replacement.
Ball milling metal replacement method, not tight to the requirement of acidity.Because the generation of metal active face is not to rely on corrosion, but relies on friction, so no acidic or basic solution still can carry out metal displacement reaction.
Ball milling metal replacement method can replace zinc with iron to its metathetical metal of displacement of some metal.
Ball milling metal replacement method is suitable for the purification of some metal, for example with the heavy metal in the zinc ball removal zinc solution.
Ball milling metal replacement method also can be removed some deleterious heavy metals in the sewage, makes sewage reach emission standard.
Claims (3)
1, replaces its substitute in solution metal and adopt Metal Ball [2].
2, the metal replacement container of solution adopts ball grinding cylinder [1], available monotubular or many combinations.
3, the precipitation metal [7] in the solution flows out with the solution [4] after replacing, through precipitation ramp pan [6] precipitation.
