Mine beneficiation plant solutions: definition and classification full analysis

Abstract: Mine processing plant solution is a complete set of technology, equipment and service system from ore to concentrate. It is not only a list of machines, but also a systematic project to maximize the value of resources. In this paper, we will deeply interpret its core connotation, and according to the process, minerals and service mode for system classification.

First, what is a mine processing plant solutions?

Mine processing plant solutions, in short, is a set of mining raw ore through a series of physical or chemical methods, efficient and economical processing into high-grade concentrate products to achieve this goal, provided from the pre-testing, engineering design, equipment supply to the construction and installation, commissioning, operation and maintenance management of a comprehensive, customized service package.

It is much more than just selling a few pieces of equipment, and its core connotations include:

• Systematic: It is a complete systematic project, covering the whole process of "coarse crushing - fine crushing - grinding - sorting - dewatering - tailings treatment", with each link closely connected and optimized.

• Customization: "There are no identical mines". Solutions must be customized according to specific ore properties (mineral composition, embedded particle size, grade, etc.), geographic environment, investment budget and product goals.

• Technology-driven: The core technology is mineral processing technology, integrating mechanical engineering, automation control, environmental protection technology and other multi-disciplinary knowledge.

• Value-oriented: The ultimate goal is to achieve the highest resource recovery rate, the lowest production costs and stable operation in line with environmental requirements, to create maximum economic benefits for the owner.

Second, the core composition of the mine processing plant solutions

A complete solution usually includes the following levels:

1. Core process technology: The "soul" that determines the sorting method and process.

2. Key equipment clusters: The "steel body" that carries the process technology.

3. Automation and intelligent control systems: The "brain" for stable and efficient production.

4. Civil engineering and plant design: the "skeleton" that supports all equipment.

5. Operation and maintenance services: the "logistics" to ensure long-term profitability.

Categorizing Mine Processing Plant Solutions

Mine processing plant solutions can be categorized from multiple dimensions, the most common ways of categorization are as follows:

Classification 1: According to the core beneficiation process principle division

This is the most basic and technical classification, which is directly determined by the physical or chemical properties of the ore.

1. Physical beneficiation solutions

   • Gravity Separation: Sorting by utilizing the difference in mineral density.

     • Applicable minerals: tungsten, tin, iron, manganese, gold, coal and so on.

     • Typical equipment: jigger, shaking table, spiral chute, centrifugal concentrator.

   • Magnetic Separation: Separation by using the difference in magnetic properties of minerals.

     • Applicable minerals: magnetite, ilmenite, tantalum-niobium ore.

     • Typical equipment: permanent magnetic cylinder magnetic separator, high gradient magnetic separator.

   • Flotation method: the use of mineral surface hydrophobicity differences in physical and chemical properties for sorting.

     • Applicable minerals: the majority of non-ferrous metals (copper, lead, zinc, molybdenum), rare metals and non-metallic ores.

     • Typical equipment: mechanical stirring flotation machine, inflatable flotation column.

   • Photoelectric beneficiation: using the difference of optical properties (color, reflectivity) of minerals, through the sensor and high-pressure air gun for sorting.

     • Applicable minerals: diamond, precious stone, ore pre-polishing waste, etc.

2. Chemical beneficiation solutions

   • Leaching: Use of chemical solvents (e.g. cyanide, acids, alkalis) to dissolve the useful components from the ore.

     • Applicable minerals: Gold, Silver, Uranium, Copper (oxidized ores).

   • Extraction-Electrowinning: Further extraction and enrichment of metals from the leach solution.

   • Roasting: Alteration of the chemical composition of the mineral by heating to facilitate subsequent processing.

Classification 2: According to the target minerals to be processed

This classification is closer to the market and the application, so that customers can quickly find out which area they belong to.

1. Ferrous metal processing plant solutions (e.g. magnetite, hematite processing solutions)

2. Non-ferrous metal processing plant solutions (e.g. copper, lead, zinc, bauxite beneficiation solutions)

3. Precious metal processing plant solutions (such as: gold, silver beneficiation solutions, often involving re-election + flotation + cyanidation)

4. Non-metallic mineral processing plant solutions (such as: quartz, feldspar, fluorite, graphite, kaolin beneficiation purification solutions)

5. Coal washing and processing solutions (e.g. coal jigging, heavy media washing, flotation solutions)

Classification III: By service mode and project scope

This reflects the capability of the solution provider and the level of customer demand.

1. EPC/M turnkey solutions

   • Definition: General contracting for the whole process or several stages of project design, procurement and construction.

   • Advantage: The owner only needs to provide resources and funds, and a single contractor is fully responsible for the quality, safety, cost and progress of the project, realizing a "turnkey" project and saving effort.

2. Core process and equipment package solutions

   • Definition: The supplier only provides the design and key equipment supply for the core beneficiation process sections (e.g. flotation plant, re-election plant).

   • Advantage: Highly specialized, suitable for projects where the owner has partial design and construction capability, but needs to introduce external technology in key aspects.

3. Modular / Mobile Plant Solutions

   • Definition: Integration of beneficiation equipment on standard container modules or trailer chassis for rapid transportation, installation and relocation.

   • Advantages: Small investment, very short construction period, high flexibility, ideal for small mines, exploration period projects or projects in remote areas.

Classification 4: By Specific Technology or Environmental Needs

This is an important classification that has emerged in recent years, reflecting the trend of the industry.

1. Dry Beneficiation Solutions

   • Characteristics: No water is needed in the whole process, and sorting is carried out by wind power, magnetic force or photoelectricity.

   • Applicable scenarios: Arid and water-scarce areas, cold areas, environmentally sensitive areas to avoid water pollution.

   • Typical cases: magnetite dry magnetic separation, coal dry wind separation.

2. Intelligent Selection Plant Solution

   • Features: Integration of IoT, big data, AI and robotics to realize automation, intelligent control and optimized decision-making in the production process.

   • Core value: Stabilize product quality, improve recovery rate, reduce energy and drug consumption, and reduce labor.
