Henan Xingyang Mining Machinery Factory has been focusing on mine concentrating equipment for more than 30 years: ball mill, flotation machine, magnetic separator, jig, jaw crusher, impact crusher, cone crusher, classifier, mixing barrel , Concentrators, feeders, dryers, vibrating screens and other whole line equipment manufacturing, the entire concentrator production line can be EPC general contracting, customer cases across the domestic provinces and abroad, Africa, Southeast Asia and other major countries in the international mineral processing.
1.FLOTATION PROCESSING PLANT
According to the differences of physical and chemical properties of ore (such as gold ore ) surface, ore flotation production line is treated by flotation reagents, the ore deposits are selectively stick to the bubbles for the purpose of separation.
Ore flotation process is divided into several parts, such as crushing, grinding and flotation etc.It will be used jaw crusher, ball mill, spiral classifier, flotation machine, the mixing tank, thickener and other equipment.

2. APPLICATION SCOPE
The plant can be used for flotation of gold ore, copper ore, lead and zinc ore, fluorite ore, feldspar ore, graphite ore, tungsten ore , other metals ore and non-metal ore etc.
c.The new flotation reagent can be used to collect ore sulfide concentrates quickly and realize efficient comprehensive utilization.
In 2017, our factory and the South African customer reached an EPC project contract of copper ore beneficiation project. The project designed capacity is 180,000 tons per year, 600 tons per day and 300 working days per year. Although the copper grade of the mine (5-13%) is not low, the complex mineral composition has become one of the difficulties of the project.
After a comprehensive analysis of test and experiment, mechanical engineers of Xingyang Mining Machinery Manufactory determined the multi-stage grinding and flotation mixed dressing method, specific include: three-stage of grinding, a roughing, secondary scavenging, and fifth concentrating .
After processing, the copper ore grade of from original 5% - 13 % increased to 90% of concentrate. The main equipment of this project includes: jaw crusher, ball mill, spiral classifiers, flotation machine, thickener, mixing tank and other equipments.
The Nissan 500-ton copper ore beneficiation equipment project is the EPC project plant customer case
The flotation chemicals that need to be used are: collectors, activators, foaming agents, etc. The collectors are used to promote gold flotation, the activators are to increase the floating velocity of the gold ore, and the foaming reagents are to increase the number of flotation bubbles.
b.Grinding fineness requirements
Generally speaking, gold contained in sulfide minerals only needs to be dissociated by sulfide ore, and special ore fineness needs to be determined by experiments.
c.Slurry concentration requirements
The principle of gold ore flotation is: flotation of large-density, coarse-grained minerals, often with a thicker pulp; conversely, when flotation of small-density, fine-grained and slime with a more dilute slurry, choose thicker crude Slurry, can guarantee to obtain higher recovery rate, choose to use more dilute concentration, help to improve the quality of concentrate.
d.Other process conditions
The process conditions affecting gold flotation include the concentration of pulp, the amount of flotation agent, the amount of aeration, the time for flotation, etc., all of which need to be determined by tests.
