How to remove lead from tin ore selection

Tin ore is an important metal ore that contains a large amount of lead. Lead removal is a very important step in the selection process of tin ore. So, how can tin ore selection remove lead? This article will introduce several effective methods for everyone.

1、 Flotation method

Flotation method is a commonly used method for tin ore cleaning and is also one of the main methods for removing lead. During the flotation process, lead is separated from tin ore through chemical reactions and physical interactions.

The specific operation steps are as follows:

1. Crush the tin ore into small particles and add it to water to make a slurry.

2. Add a certain amount of flotation agent to make the lead mineral particles in the pulp float to the water surface to form foam, while the tin mineral particles sink to the bottom.

3. Collect foam and get lead concentrate after a series of treatment.

2、 Reselection method

The gravity separation method is also a commonly used method for tin ore selection, which can effectively remove lead. During the gravity separation process, lead is separated from tin ore through physical actions such as gravity and centrifugal force.

The specific operation steps for are as follows:

1. Crush the tin ore into small particles and add it to water to make a slurry.

2. Separate minerals of different particle sizes from the slurry through a series of screening, washing, and other steps.

3. Sort the separated minerals according to their density and separate lead minerals from tin minerals.

3、 Heavy float method

Heavy flotation method is a combination of gravity separation and flotation methods, which can effectively remove lead. In the process of heavy flotation, lead is first separated from tin ore by gravity, and then collected by flotation.

The specific operation steps are as follows:

1. Crush the tin ore into small particles and add it to water to make a slurry.

2. Separate minerals of different particle sizes from the slurry through a series of screening, washing, and other steps.

3. Sort the separated minerals according to their density and separate lead minerals from tin minerals.

4. Add the separated lead minerals into the flotation agent to make them float to the water surface to form foam, and then collect them to obtain lead concentrate after a series of treatment.

summary

Lead removal is a very important step in the tin ore beneficiation process, which can be carried out using methods such as flotation, gravity separation, and heavy flotation. During the operation process, it is necessary to pay attention to controlling the amount of flotation agent and controlling the pH value of the slurry to ensure the effectiveness of lead removal.
