Product Details

Lithium Ore Production Line Solution provides advanced processing technologies for Spodumene and Lepidolite ores.

We offer diverse process routes including Flotation, Magnetic Separation, and Heavy Media Separation (HMS). Our solutions are designed to maximize recovery rates (>85%) while reducing operational costs by up to 40%.

What Is Lithium Ore Beneficiation?

Lithium Ore Beneficiation involves upgrading raw lithium minerals (mainly Spodumene and Lepidolite) to commercial-grade concentrate (typically SC6.0, i.e., 6% Li₂O). The process removes impurities like iron, quartz, and feldspar. The most common method is Flotation, often combined with Magnetic Separation to remove iron and Heavy Media Separation for coarse particle recovery.

Lithium Beneficiation Process Methods

Method 1: Flotation Separation (Mainstream)

Best for fine-grained disseminated ores (Spodumene/Lepidolite).

Positive Flotation:

Conditioning: High alkali environment (NaOH).
Desliming: Removing fine slime to save reagents.
Separation: Using Oleic Acid collectors to float Lithium directly.

Reverse Flotation:

Using lime and starch to inhibit Lithium minerals while floating gangue (quartz/feldspar) using Cationic collectors.

Method 2: Magnetic Separation (Iron Removal)

Goal: Remove magnetic impurities (Iron, Tourmaline) to improve concentrate quality.

Weak Magnetic Sep (0.6-0.8T): Removes strong magnetic iron.
High Gradient Magnetic Sep (1.4-1.8T): Removes weak magnetic impurities like mica and tourmaline.
Result: Low-iron Spodumene concentrate.

Method 3: Heavy Media Separation (HMS)

Applicable: Coarse-grained Spodumene.

Principle: Using heavy suspension (Ferrosilicon) in a Dense Media Cyclone.
Performance: Reduces grinding cost by 40% by discarding waste rock early.

Frequently Asked Questions (FAQ)

Q1: What is the standard grade for Lithium Concentrate?

A: The industry standard for Spodumene concentrate is SC6.0, which means it contains 6.0% Li₂O. However, grades like SC5.5 are also traded depending on market demand.

Q2: Why use Heavy Media Separation (HMS)?

A: HMS effectively removes waste rock at a coarse particle size before grinding. This reduces the volume of material entering the ball mill, saving up to 40% in grinding energy costs.

Q3: How to remove Iron from Lithium concentrate?

A: Iron is a critical impurity for battery-grade lithium. We use High Gradient Magnetic Separators (1.4T+) to remove weak magnetic minerals like tourmaline and iron-bearing mica.
