Case Study: 5TPH Alluvial Tin Processing Plant In Nigeria

JXSC Case Study: 5TPH Alluvial Tin Ore Processing Plant In Nigeria

 

1. Project Overview

The Tin raw ore is an alluvial type, with much sticky clay. The tin concentrate particle size is 0-15mm.

The plant will be installed in Nigeria, the client wants a simple operation and easy maintenance washing plant, which can wash 5 tons per hour. The customer site has enough height difference to install the machines.

 

2. Raw Ore Information

The raw ore tin has a maximum feed size of 50 mm. The concentrate particles are mainly fine, with sticky clay.

 

3. Processing Capacity Requirement

The client required a processing capacity of 5 tons per hour, with the possibility to upgrade to 10 TPH in the future.

 

4. Our Process Design & Solution

Process Flowchart

Nigeria 5TPH Alluvial Tin Plant Flowchart 

Process Description:

1. The loader or excavator feeds raw ore into the scrubber trompet. The trommel scrubber is used to wash off clay from ore and screen out particles of different sizes.

2. Overscreen materials of the trommel naturally fell to one side. This is waste sand.

3. Underscreen materials of the trommel are sent to the pemisah jig.

4. The shaking table will recover the tin again, to recover as much tin as possible.

Main Equipment List:

• Penggosok trombon
• Pemisah jig
• Meja goyang  
• Pemisah magnetik
• Pumps & Slurry Pump
• Diesel Generator & Control Panel

 

 5. Customer Questions & Our Answers

(1) After treament how many % can be achieved?
This depends on the grade of the customer’s raw ore; generally, after processing with our equipment, the grade can reach over 60%.

(2) Why use a trommel scrubber instead of a trommel screen for washing?
We determine whether to use a trommel scrubber machine or a trommel screen based on the customer’s mining site conditions. The layar trompet is very good for washing materials without sticky clay, and tormmel scrubbe is very good for washing materials with sticky clay. In this customer’s case, the material at their mining site is very hard to clean, with lots of sticky clay.

(3) Why use the jig separator instead of the spiral chute?
Generally, saluran spiral are suitable for recovering chrome concentrate in the 0-2mm size range, while jigging machines are suitable for recovering chrome concentrate containing larger particles.
This customer’s chrome concentrate is basically over 0-2mm, so using a jig separator is more suitable and can recover as much tin concentrate as possible.

(4) What’s the warranty?
The warranty period is 12 months, commencing from the date the machines’ main parts arrive at Monrovia Port, Liberia (Excluding wear-and-tear parts).
① All goods are 100% brand new upon leaving the factory. Should the client wish to replace any original parts of the machine, prior consultation with JXSC is required to prevent potential issues.
② Should the client require any wear-and-tear parts, we can supply them in the shortest possible time.
③ In the event of any operational issues with the equipment, we provide online technical support to assist customers in resolving problems.

(5) Why use 3 disc magnetic separator after the shaking table?
The main reason for using a three-disc magnetic separator after the tin ore processing meja goyang is to further improve the grade of the tin concentrate, remove impurities such as wolframite and ilmenite, and simultaneously recover these valuable minerals.
Specifically, the tin concentrate enriched by gravity separation sometimes does not meet the smelting requirements. In this case, a magnetic separator can be used to further purify the gravity-separated crude concentrate. The three-disc magnetic separator can separate multiple impurities in a single pass, and its magnetic field strength is adjustable, reaching up to 22,000 Gauss, making it suitable for the separation of tantalum, niobium, tungsten, and tin ores.

(6) If we need an engineer, how many days we need and how much?
If the buyer needs JXSC to send an engineer to the mine site for installation &commissioning guidance, need the following extra cost:
① The engineer’s salary is about $150/day/person; installation time depends on the customer’s mine site preparation conditions.
② Round-trip ticket cost
③ Visa application cost
④ Any other potential cost before or after the installation period, such as hotel costs, waiting for a flight, etc.
⑤ Arrange food
Generally, it takes 1-2 months, and we recommend sending two engineers.

(7) Will you provide instruction manuals?
Yes, after the customer orders the machines, we will provide all machine instruction manuals.
And also will provide the plant detail layout drawing, foundation drawing, and each main machine’s drawings & machine.
