The significance of mineral processing cannot be overlooked in this era of urbanization and industrialization. Therefore, its market size is likely to reach USD 274.26 billion by the year 2032. Have you ever thought about why mineral processing is essential? The purity of non-metallic minerals refers to the mineral composition and not the chemical composition. Moreover, the profitability of a mine depends on the concentration of the desired material that can be extracted from the ore. 

The naturally produced non-metallic ores indeed consist of a lot of mineral impurities in varying degrees. While some mineral products may be allowed to exist, others need to be removed. That is where mineral processing plants and separation systems come into the big picture. Mineral processing plays a crucial role in ensuring the maximum yield of the desired concentrate before the product reaches the market. 

In this blog, you will delve into everything about mineral processing plants and separation systems. Let’s dive in!

An Overview of the Mineral Processing Plant

A mineral processing plant refers to a dedicated space for processing ores and converting the raw ores into high-grade mineral products. The core aim is to separate valuable minerals from the waste rocks through a series of chemical or mechanical systems for further use. These plants are capable of processing various non-metallic ores like feldspar, quartz, limestone, fluorite, and more. 

Role of Process Plants in Improving Mining Efficiency

The process plants focus on maximizing mineral recovery through the integration of several processing and separation stages. They make use of advanced technologies like flotation, filtration, and dewatering to enhance output while lowering operation expenses. The best part is that the modular process plants can be effectively tailored to meet different mining needs, offering greater scalability and flexibility. 

The Four Stages of Mineral Processing

Recovering valuable minerals and metals from run-of-mine ore has become more essential than ever before. That is why mineral beneficiation is crucial. Delve into the key stages involved in this process!

Comminution

This step involves the grinding and crushing of the large ores into smaller pieces with the help of appropriate equipment. The main goal is to make them fit for further processing down the line. 

Sizing

The second stage in mineral processing is the separation of ore particles on the basis of their sizes. The most common sizing method used by mineral processing plants is screening. This approach allows the rock pieces to pass through one or more screens and makes it easier to sort them effectively by size. 

Concentration

Concentration is indeed at the core of mineral processing. This step focuses on separating the valuable mineral components from gangue or waste rock and removing unwanted impurities. It involves breaking down of the materials until the specific concentration of minerals is reached.

Dewatering 

The final step of mineral processing is all about getting rid of the water content of the mineral through drying, filtration, and other methods. The main objective of this stage is to prepare the minerals for transport and further processing. 

Mineral Separation Systems

There are several techniques used for the separation of valuable minerals from waste rocks. Take a look at the most common mineral separation systems leveraged in the plants!

Gravity Separation

This technique helps separate the non-metallic minerals on the basis of the difference in gravities. Gravity separation works best for the heavier metals.

Froth Flotation

Froth flotation makes use of a chemical collector and frother to form bubbles on the slurry surface that bind the hydrophobic materials. In the next phase of this process, the bubbles are collected from the frother surface. The mineral processing plants may leverage activators to allow the flotation of mineral ores. On the other hand, they may even use depressants to inhibit gangue flotation. 

Magnetic Separation

It is a common perception that magnetic separation is used for metallic ores only. However, this technique also proves to be beneficial for the separation of non-metallic minerals. Magnetic separation is indeed helpful in the removal of magnetic impurities present in non-metallic minerals. 

This process takes place in a magnetic separator where the slurry is made to pass through a magnetic field. When the non-metallic minerals enter the separation space, the magnetic minerals get attracted while the non-magnetic minerals remain unaffected. As a result, separating the pure non-metallic minerals becomes easier. 

Environmental Benefits of the Modern Separation Systems

Today, reducing the negative impact on the environment has become a top priority for industries. Therefore, mining companies make use of non-metallic mineral beneficiation systems that can help lower energy use, water consumption, and waste material generation. By reducing waste and enhancing resource recovery, modern systems can significantly contribute to the betterment of the environment and ensure more sustainable mining operations. 

Choosing the Right Separation System

No doubt, several non-metallic mineral separation systems exist. However, the selection of the right system matters a lot for enhanced outcomes. When choosing separation systems, mining companies need to factor in aspects like the type of ore to be processed, environmental compliance requirements, and the necessary recovery rate. 

Also, companies must get an idea about the maintenance requirements of the separation systems, their compatibility with the existing processing equipment, and ease of use. Make sure to invest in systems that are energy efficient, scalable, and capable of conserving water. 

Understanding the Mineral Processing Equipment

By now, you must have an idea of the mineral processing plants and separation systems. However, to carry out the processing, several pieces of mining plant equipment are used. Delve into the most common equipment!

Crushing Equipment

Jaw crushers are usually used for primary crushing that allows the reduction of the abrasive and hard materials into smaller particles. On the other hand, cone crushers prove to be beneficial for secondary and tertiary crushing. 

Grinding Equipment

Grinding helps further reduce the size of the crushed ores into ideal particle sizes and helps in the release of valuable minerals. The different grinding equipment may include rod mill, ball mill, and autogenous mill. 

Mineral Processing Equipment

The mineral processing equipment may include the flotation machine, magnetic separator, shaking table, and spiral chute. The flotation machine allows the separation of minerals through the use of bubble buoyancy and mechanical agitation. 

The magnetic separators work by separating minerals based on their magnetic property differences. On the other hand, the shaking table makes use of water flow and horizontal vibrations for separating minerals on the basis of density. Finally, the spiral chute leverages centrifugal and gravity forces for the separation of minerals. 

Screening Equipment

The key goal of the screening equipment is to classify ore particles in different stages of processing. It mainly includes the vibrating screen and trommel screen.
