Process flow of placer tin ore and introduction of beneficiation equipment

Placer tin ore refers to the tin deposits that are located in or near rivers, streams, and beaches. The beneficiation process of placer tin ore is often complex due to the presence of various minerals and impurities. Here is a general process flow and introduction to some common equipment used in placer tin ore beneficiation:

1. Screening: The raw placer tin ore is washed and screened to remove large rocks, boulders, and other debris.

2. Gravity Separation: The tin ore is then separated from other heavy minerals using various gravity separation methods such as jigs, spiral separators, and shaking tables. The main purpose of this step is to concentrate the tin ore.

3. Magnetic Separation: The tin ore concentrate is then subjected to magnetic separation to remove any remaining magnetic minerals such as magnetite and hematite.

4. Chemical Beneficiation: Chemical beneficiation methods such as leaching and flotation may be used to further remove impurities such as iron, sulfur, and arsenic.

5. Smelting: After beneficiation, the tin ore concentrate is smelted to produce pure tin metal.

Here are some common equipment used in placer tin ore beneficiation:

1. Trommel Screen: It is used for washing and screening of raw placer tin ore to remove large rocks, boulders, and other debris.

2. Jig Separator: It is used for gravity separation of tin ore concentrate from other heavy minerals. The most commonly used model is JT3-2 with an estimated price of $5,000-$20,000.

3. Spiral Separator: It is used for gravity separation of tin ore concentrate from other heavy minerals. The most commonly used model is 5LL-1200 with an estimated price of $1,500-$3,000.

4. Shaking Table: It is used for gravity separation of tin ore concentrate from other heavy minerals. The most commonly used model is LY-3000 with an estimated price of $3,000-$10,000.

5. Magnetic Separator: It is used for magnetic separation of the remaining magnetic minerals in the tin ore concentrate. The most commonly used model is CTB-1024 with an estimated price of $10,000-$30,000.

6. Flotation Machine: It is used for chemical beneficiation of tin ore concentrate to remove impurities. The most commonly used model is XCF/KYF-4 with an estimated price of $10,000-$30,000.
