120TPD Spodumene Lithium Ore Processing Plant in Zimbabwe

JXSC has provided a full set of 120TPD spodumene lithium ore processing plant in Zimbabwe, including crushing, grinding, flotation, lithium concentrate dehydration system, and auxiliary equipment.

This customer provided their material information as follows:

• The type of lithium ore is spodumene
• The maximum ore feeding size is 100mm
• Processing capacity is 5tph (120 tons per day)
• Lithium grade in raw ore: no data, the customer didn’t ore sample test.

1. Crushing System (designed to produce about 10 tons per hour, 12 hours of production per day)

The ore in the raw ore bin is fed into a jaw crusher for coarse crushing through a chute feeder, and is transported to a secondary jaw crusher for fine crushing by a belt conveyor. Fine crushed materials are sent to a vibrating screen(with one deck,20mm mesh size), sieve out the material of 0-20mm and more than 20mm, the material of more than 20mm is returned to the secondary jaw crusher through the return material belt conveyor for recrushing. All 0-20mm materials from the vibrating screen are transported to the silo by the belt conveyor for standby.

2. Mineral dressing process (designed to produce 5 tons per hour, 24 hours a day)

The beneficiation process adopts one-stage ball milling and three-stage flotation.

• Ball mill – Smaller than 20mm materials enter the ball mill for grinding operation, the grinding concentration is 25%-35%, and the grinding particle size is 200 mesh, accounting for 75%. The spiral classifier is used to form a closed circuit. The overflow slurry of the spiral classifier is pumped to the mixing tank and the dosing system, and then sent to the flotation machine.
• Flotation machine – The flotation machine is divided into one stage of rougher, one stage of scavenging, and three stages of concentration operations. The working principle of the flotation machine is: the impeller is driven by the V-belt drive of the motor to rotate, and centrifugal action is generated to form a negative pressure. On the one hand, sufficient air is sucked in to mix with the ore pulp; on the other hand, the ore pulp is stirred to mix with drugs, and at the same time, the foam is refined to make the mineral sticky. Above the combined foam, it floats to the surface of the slurry to form a mineralized foam. Adjust the height of the ram to control the liquid level so that the useful foam is scraped off by the scraper. After three stages of concentration operations, high-grade lithium concentrate can finally be obtained.

3. Treatment of lithium concentrate dehydration

Lithium concentrate adopts a two-stage dehydration process. One deep cone thickener is used for the first stage of dehydration, and one set of Disc vacuum filters is used for the second stage of dehydration. The water content of the lithium concentrate is about 15% after dehydration, and the concentrate can be bagged for sale after dehydration.

1. What’s the recovery for the lithium concentrate?
Answer: 90% up

2. What chemicals are needed to process lithium?
Answer: Chemicals are needed for processing spodumene lithium ore as follows:
sodium hydroxide(NaOH),
sodium carbonate（Na2CO3）,
Sodium hexafluorosilicate,
Oleic acid + Oxidized paraffin wax soap(2:1),
2# Flotation oil

3. Can you help me source these chemicals?
Answer: Sure, we can recommend the chemicals supplier to you

4. Can you send an engineer to install this lithium plant? I can only buy this plant machine on the condition that you send your engineer for installation.
Answer: Of course, we can send an engineer to help our customer complete the installation if you need. You just need to pay the engineer’s salary of $150 daily, also need to be responsible for round-trip tickets, visa fee, meals, and lodging for our engineer.

5. Can you provide spare parts for this plant?
Answer: Sure, we can provide spare parts as per your requirement
