  • Zn + Cu2+ Zn2+ + Cu

    Cu Zn E Eo cell cell If E is for whole cell, then Q looks like K for the complete balanced reaction and Eo is Eo cell This can also be for half cells In this case, Q is the expression in the Eo (reduction) equation, i.e., reduced over oxidized. For example [ ] [ ] log 2 0.059 ( ) [ ] 1 log 2

  • pH Ranges for Sequential Cu Pb Zn Flotation Separation

    Float Metals One by One Selectively Since our objective is to sequentially float Copper, then Lead, than Zinc while rejecting Pyrite, let us explore how we can separate Cu/Pb/Zn from Fe pH 6 6.5 is where Pb/Zn/Fe are least hydrophobic while Cu is most hydrophobic. Great pH to Recover Cu. pH 7.5 8 is where Zn/Fe are least hydrophobic while Pb

  • Techniques in Underground Mining ILO Encyclopaedia

    The stope face is a 5.0 m vertical wall across the stope with a 0.5 m open slot beneath it. Five meter long horizontal holes are drilled in the face and ore is blasted against the open bottom slot. The tonnage produced by a single blast depends on the face area and does not compare to that yielded by the overhand stope blast.

  • CU2+ + Zn gt; Cu + Zn2+ I need help with my homework

    Cu^2+ + Zn gt; Cu + Zn^2+ Break up into 2 reactions, one reaction showing the oxidation and the other is showing the reduction Cu^2+ + 2e gt; Cu reaction in which copper is being reduced this is the oxidation rxn. Zn gt; Zn^2+ + 2e reaction in which zinc is being oxidized this is the reduction rxn . 2 electrons exchanged per copper atom

  • stoping mining methodflow line production

    Types of Underground Mining Method Comparison. RillCut Stoping Mining. Rill cut, or rill stoping, as shown at B, Fig. 2, has the principal advantage that when filling is used it can be run down through a raise at the apex of the stope and will fill the stope without shoveling.

  • Removal of Cu(II), Zn(II) and Pb(II) from water using

    The results of adsorption studies carried out as a function of contact time, for Cu 2+, Zn 2+ and Pb +2 were presented in Fig. 3a. It suggested that the removal of Cu 2+, Zn 2+ and Pb 2+ by the maghemite nanotube adsorbents took place in two distinct steps a relatively slow phase (first 40 min), followed by a increase until the equilibrium was
