In the Vietnamese gold mining market, the application prospects of flotation technology and its equipment are relatively broad, especially in the treatment of complex ores and the improvement of gold recovery rate. The following is an analysis of the application prospects of flotation technology in the field of gold mining in Vietnam:

Overview of gold mining resources in Vietnam
Vietnam has a certain amount of gold resources, mainly distributed in the north (such as Lao Cai Province, Laizhou Province), the central plateau and parts of the south.
The types of gold mines are mainly quartz vein gold mines and gold-bearing polymetallic sulfide ores. Some ores are complex and have more associated metals.
The overall local mining technology in Vietnam is at a medium-low level, and it is urgent to introduce advanced mineral processing technology to improve resource utilization efficiency.
The role of flotation technology in gold mines
Flotation is a physical and chemical method for separating useful minerals from ores, especially suitable for:
Gold-bearing sulfide ores
Such as pyrite, chalcopyrite, sphalerite, etc. contain gold, which needs to be enriched by flotation.
Associated gold ore
Gold coexists with copper, lead, zinc, etc., and needs to be recovered by combined flotation technology.
Complex and difficult-to-process gold ores
Such as muddy, fine-grained, ores with different oxidation levels, often require a combined flotation-gravity-heap leaching process.
Analysis of the demand for flotation equipment in the Vietnamese market
1. Technical level demand
Improve the recovery rate and concentrate grade of gold;
Improve the ability to process complex or low-grade ores;
Achieve environmentally friendly and energy-saving mineral processing processes, reduce pollution and energy consumption.
2. Applicable product types of flotation equipment
A. XCF/KYF type aerated flotation machine
Applied to the main flotation process of medium and large mineral processing plants.
Suitable for expansion or new construction of mines, with high investment.
B. SF type mechanical agitation flotation machine
Applied to small and medium-sized mines or roughing processes.
Low cost and wide application.
C. Microbubble flotation column/reverse flotation equipment
Applied to difficult-to-process ores and tailings recovery.
Belongs to emerging demand with great potential.
D. Automatic dosing system for flotation reagents
Applied to improve flotation efficiency and reduce manpower.
It is a potential growth point in the future market.
Challenges and opportunities
Challenges
Some mining areas in Vietnam have limited electricity and water resources, and customized energy-saving equipment is needed;
Technical personnel have different levels and need supporting training and services;
Laws and environmental protection requirements are becoming increasingly stringent, and equipment must meet green mine standards.
Opportunities
The Vietnamese government encourages deep processing of resources, and the entry threshold for foreign investment is gradually lowered;
Local companies are more willing to upgrade mid-to-high-end equipment;
Chinese mining equipment is cost-effective and has good market competitiveness.
