Use of combined agents in the separation of lead and zinc ore

When flotation collector lead-zinc ore with thio compounds, lead and zinc are almost always lead zinc depressant solutions. There are two main types of separation methods: cyanide and non-cyanide.
1. Cyanide method: There are few cases of cyanide alone, and usually always cooperate with other inhibitors. For example, cyanide is often used in combination with zinc sulfate. However, cyanide is toxic and dissolves gold and silver . In recent years, many mines have switched to non-cyanide methods, or zinc sulphate has been used in combination with less cyanide.
2. Non-cyanide method: The main agents used in the non-cyanide method are H 2 SO 3 , Na 2 SO 3 , ZnSO 4 and SO 2 gases. For example, a lead-zinc-sulphur mine adopts a preferential flotation process. When floating lead, ZnSO 4 + Na 2 SO 3 (1.4:1) has been used to suppress sphalerite. Compared with cyanide method, lead concentrate grade and recovery rate, zinc concentrate Both the grade and the recovery rate have been greatly improved.

1.5 Ton Pedestrian Type Electric Stacker

Zowell 1.5ton standing on Electric Stacker, is an industrial device for loading and lifting pallets on a shelf at high level. As an ideal choice to operate in narrow space of warehouse, it can be widely used in petroleum, chemical, pharmaceutical, textile, pigment, coal and other industries, as well as ports, railways, freight yards, warehouses.

Compared with the traditional manual stacking, Zowell full electric stacker maintains great advantages in safety, efficiency and cost. In addition to durability and accuracy both outside and inside, Zowell XE electric stackers are also equipped with mast with clear view, double speed and lateral vertical moving switch, which are valuable when working in limited space.


Detail features

1. Multifunctional handle
The multifunctional handle is imported from Germany. It has integrated control functions including a speed button, horn button, emergency reversing button and lifting button. The handle has an emergency reversing button which can effectively protect the operators from being hurt in accident involving falling items. The handle can realize braking both in vertical and horizontal position. The human-machine design is quite safe and the operation is more comfortable.

2. Strong power
This stacker adopts high efficiency motor which can be precisely controlled and the output power is strong. The turning control can be optionally equipped with EPS. It can help the driver with turning by using electronic control device to produce auxiliary power of relative level and direction according to the torque signal and speed signal. So the operation of the driver can be more convenient and precise and the movement can be more stable and reliable.

3.Superior gradeability
The powerful motor and 5 wheel stacker structure can provide superior stability and gradeability, so that the truck can have sufficient gradeability when it is fully loaded.

4. Buffered pedal
The foldable pedal can save space when the stacker is not in use. It can also effectively protect the drivers from being effected by the bumping and give feedback to the driver with the road condition.

5. Dual balance wheel device
This stacker is equipped with a dual balance wheel so that it can overcome roadblocks easier and the running can be more stable.

6. Emergency power-off switch
The power can be rapidly cut off in emergency to ensure safety.
