Bolivia 3000t/d Tin Project

Entrusted by the customer,Jinpeng undertook dressing experiment research, engineering design, parts of equipment supply, installation and debugging, etc. Through the design institute and laboratory research, finally decided to adopt flotation +gravity method,and this projects was highly praised by the Bolivian President, whom went to the site for opening ceremony and started the equipment operation by himself.

Project Process


1.Crushing and screening:Crushing the raw ore to 20 mm, after screening, divided into two grade:20 ~ 4mm and 4 ~ 0 mm.

2.Pre-leaching:Will be 20 ~ 4 mm ore into the cyclone for primary selection, then go to the rod mill ,and then use jig, vibration screen will be used to remove + 2 mm ,for- 2 mm will go to shaking table.

3.Mixed flotation: jig and shaking table concentrates to be milling separately, and then for mixed flotation, mixed flotation tailings will go to shaking table for the qualified tin ore concentrate.

4.Separation flotation, after regrinding the mixed flotation concentrate ,will do the lead and zinc flotation separation, which we can get lead antimony concentrate and zinc concentrate respectively.

5.Gravity: slurry go through Φ300 mm hydrocyclone ,overflow to 125 mm and 75 mm hydrocyclone,the setting sand goes to thickener,flotation desulfurization for tin flotation.


We have a very strict management for each project, and one people will be responsible for each project from the beginning to the end,which can make sure the whole process smoothly.

Design institute will start from engineering design, precise positioning technology and its products, not only guarantee the technology, but also reduce customer cost and choose the best process.

At the same time, we have a very strict quality management for equipment production,and have passed the ISO 9001:2008 international quality certification. Several large automatic CNC cutting machine, CNC automatic welding machine, 5 meters CNC vertical lathe, CNC lathe, CNC boring machine, and has the longest 15 meters large lathe in Shandong, all of this can guarantee the accuracy of the equipment and the appearance of fine quality.
