Technological process for selecting seaside tin ore

Seashore tin ore is an important metal ore with high tin content and excellent quality, making it an important raw material for manufacturing tin ware, alloys, and other products. In the beneficiation process of coastal tin mines, certain technological processes need to be adopted to improve beneficiation efficiency and reduce production costs. This article will introduce the process flow of selecting seaside tin ore, helping readers understand the beneficiation process of seaside tin ore.

1、 Characteristics of Seashore Tin Mines

Seaside tin ore is a kind of ore with high hardness, whose main components are cassiterite, Scheelite, Wolframite, Galena, etc. Among them, cassiterite is the mineral with the highest tin content, and its tin content can reach over 60%. The characteristics of seaside tin ore are fine mineral particle size, high ore hardness, high impurity content, and high difficulty in beneficiation.

2、 The beneficiation process flow of seaside tin ore

1. Rough selection

The rough separation process of the seaside tin ore is mainly achieved by gravity separation, which separates the larger particles and heavier minerals from the ore. The specific process is as follows:

(1) Ore crushing: Crushing the raw ore through a crusher to make its particle size suitable for entering the gravity separator.

(2) Gravity sorting: The ore is placed in a gravity sorting machine, and through the action of gravity, larger particles and heavier minerals are separated. The focus of this step is to adjust the parameters of the gravity separator so that it can separate the most cassiterite and a small amount of impurities.

2. Selected

The flotation process of coastal tin mines mainly involves separating cassiterite and other minerals from the ore. The specific process is as follows:

(1) Reagent addition: Add the reagent to the ore to generate bubbles on the surface, separating cassiterite from other minerals.

(2) Flotation: Place the ore added with the reagent into a flotation machine and separate cassiterite and other minerals through the action of bubbles. The key to this step is to control the dosage of reagents and the parameters of the flotation machine to achieve the best separation effect.

3. Selection

The selection process of coastal tin mines mainly involves gravity separation and flotation, which further separates the cassiterite from other minerals in the ore to improve the purity of cassiterite. The specific process is as follows:

(1) Gravity sorting: Put the separated cassiterite and other minerals during the selection process back into the gravity sorting machine, and further separate the cassiterite and other minerals through the action of gravity.

(2) Flotation: Put the separated cassiterite and other minerals from the gravity separation process into a flotation machine, and further separate the cassiterite and other minerals through the action of reagents. The key to this step is to control the dosage of reagents and the parameters of the flotation machine to achieve the best separation effect.

3、 Summary

The beneficiation process of seaside tin mines requires the use of certain technological processes to improve beneficiation efficiency and reduce production costs. Among them, roughing, middle concentration and concentration are the three Committed step in the beneficiation process of seaside tin ore. By adjusting the process flow and parameters reasonably, the beneficiation efficiency of coastal tin mines can be maximized, thereby achieving better economic benefits.
