Preface
With the development of modern technology and industry, the requirements for mineral raw materials are becoming higher and higher. The raw ore directly mined often does not meet the standards, and the raw ore can meet the requirements after processing. The beneficiation technology has been applied in the metallurgy, coal, chemical, building materials and environmental protection sectors, which is of great significance to the development of the national economy.
HT for Web has not only independently developed a powerful HTML5- based 2D and 3D rendering engine, which provides rich display effects for visualization. Between 2D configuration and 3D configuration , Hightopo (hereinafter referred to as HT) has a wealth of configuration options on the HT for Web product. This article will introduce how to use HT's rich 2/3D configuration to build one Visualization of the beneficiation process.
Interface introduction and effect preview
We use the 2D/3D engine independently developed by HT for Web to realize the visualization of the beneficiation process and visualize the process of the beneficiation process. The Demo contains the beneficiation scene and the data display panel. As shown below:

The interface supports internationalization. (You can select the language of the current page through the Chinese-English switch button in the upper right corner)
The loading and rendering of the scene model takes a certain amount of time. For this reason, we set up a loading animation, and the scene rendering time is indicated by a progress bar.
Both sides include the middle chart, including basic line chart, histogram, table (automatically scrolling content), pie chart, radar chart, etc., with their own dynamic effect demonstrations.
The middle scenes include some equipment models that need to be used in beneficiation, and the production route from raw ore to industrial raw materials that can be used. The entire process of beneficiation technology is presented to us in the most intuitive way. The UV offset animation of the model texture is used to simulate the transfer process of mineral materials. The scene also has functional interaction with the drawing buttons, such as the beneficiation roaming (mining process flow), the whole field roaming (the scene is viewed around the field), the start and stop animation demonstration of the thickener and the ball mill, and the individual viewing of six types of beneficiation equipment.
Beneficiation roaming:
The beneficiation process animation process, from ore crushing to screening to ore grinding, classification and other operations roaming animation, let us get a closer view of each step of the beneficiation operation.
Each job animation stays for 5s by default, and then goes to the next animation. We can also control the animation playback by clicking the control bar button.
Close: End the beneficiation roaming animation and return to the initial view of the page
Previous step: Run the previous animation process
Next step: Run the next animation process
Pause: Stop the current animation, and continue the animation by clicking [Previous] [Next]
5s timing bar: timing of screen stay time
Full roam:
Navigate the scene by changing the angle of view around the field. (You can stop the animation by clicking the view reset button).
Start and stop of thickener and ball mill:
By modifying the angle of model rotation every second, the animation effect of slow stop or slow start of machinery and equipment can be achieved.
Device view:
By default, six kinds of machine equipment are provided for viewing. You can select and view through the upper radio button group. After selecting a certain device, the scene will blur all other devices, and the viewing angle will be zoomed in to the selected device, and it will be on the right. The device introduction panel pops up on the side.
Exit viewing: Click the close button in the upper right corner to return to the viewing angle before viewing the device, displaying all models of the original scene.
Introducing panel dynamic analysis: The panel belongs to a billboard 3D bulletin board primitive in the scene, and we use several built-in style attributes (cutting direction, cutting scale, transparency) of the dynamic effect.

Realize value
There are not many rich ores that can be directly used for smelting in nature, especially with the development of industrial production, the reserves of rich ores are gradually decreasing, so more and more lean ores have to be mined. However, smelting with low-grade lean ores is uneconomical. In order to reduce the cost of smelting, effectively extract useful components in the ore, and comprehensively utilize national resources, the ore mined from the mine must be processed before smelting.
Beneficiation is based on the physical and chemical properties of different minerals in the ore. After the ore is crushed and finely ground, gravity separation, flotation, magnetic separation, electric separation and other methods are used to separate useful minerals from gangue minerals and make A process in which various symbiotic (associated) useful minerals are separated from each other as much as possible to remove or reduce harmful impurities to obtain raw materials required for smelting or other industries. Among the products, those with enriched useful ingredients are called concentrates; those with enriched useless ingredients are called tailings; those with useful ingredients between concentrates and tailings are called medium ore that requires further processing. Beneficiation is a continuous production process consisting of a series of continuous operations, including preparation operations, sorting operations, and product processing operations.
- Preparation work: This work includes crushing and screening, grinding and grading. The main purpose is to separate useful minerals from gangue minerals, and useful minerals from useless minerals to prepare for the separation of monomers. This kind of preparation is to divide the material into a number of suitable grades to prepare for the sorting operation.
- Beneficiation operation: This is the key operation (or main operation) of the beneficiation process. It adopts different beneficiation methods according to the different properties of minerals, such as flotation, gravity separation or magnetic separation.
- Product processing operations: mainly include concentrate dewatering and tailings processing. Concentrate dehydration usually consists of three stages: concentration, filtration, and drying (sometimes required). Tailings treatment usually includes tailings storage and tailings water treatment.
In the process of beneficiation, the various components of the original ore are separated. In addition to the production of useful minerals, other materials can also be turned into treasures, such as waste fly ash from thermal power plants. The piled up land and causes environmental pollution are the power plants’ A major disadvantage, and the beneficiation of fly ash can produce many useful products such as iron ore, glass beads and cement ingredients. Of course, in the process of beneficiation, environmental pollution problems such as harmful gases, water pollution, and solid waste cannot be ignored. Corresponding treatments are required. For example, the beneficiation wastewater is discharged after precipitation treatment or activated carbon adsorption treatment reaches the standard.
to sum up
From mine automation to digital mines, to today's smart mines, in the era of digital economy, the concept of future mine construction and realization methods is constantly being refreshed. Along with the "new infrastructure" boom, it has been confirmed that the main way for the transformation and upgrading of the mining industry is the application of modern information technologies such as big data, artificial intelligence, cloud computing, and mobile internet. The emergence of smart mines, smart exploration, and the mining Internet of Things is leading the accelerated development of traditional mining in the direction of green, safe, smart and efficient.
In 2019, Tupu Software HT enhanced the implementation and application of WebGL- based 3D GIS technology in the fields of water conservancy, chemical industry and mining, and introduced the aerial photography 3D modeling solution on the basis of traditional modeling to solve problems such as chemical parks and mines. This kind of scene area is large, the traditional 3dsmax maya and other tools manual real-world modeling workload is huge, through drone aerial photography, plus post data processing, seamless integration of HT original 3D model, a good solution to the macro and micro The demand for integration and integration.
In the mining field, Tupu HT and its partners successfully implemented the 3D visualization integrated operation and maintenance system of Zijin Mining's global multinational mine sites:
