Mining Filtration Equipment

Filters used in mining and metallurgical processing generally are engineered with characteristics specific to application in this industry. Compositech manufactures horizontal belt filters, disc filters, and drum filters that are used extensively in mining filtration equipment applications and mining and metallurgical processing.

Compositech is a leading manufacturer of mining filtration equipment. We manufacture horizontal belt filters and mining filter presses, with several of our filters currently in operation in high tonnage, heavy industries including mining and metallurgy.

The Compositech horizontal belt filter line features tubular frames for ease of cleaning and special corrosion resistant materials are used in filter construction and for coatings. We use non-lubricated FDA approved polymer bearings, fully enclosed troughing supports, full coverage drip pans with flanged drains, and fully encapsulated drainage belts. Our horizontal belt filters are available in widths up to 4 meters wide. Our largest horizontal belt filter is a modular system that can be sized and resized according to customer needs. Each module is 2.5 meters long and increases the filtration area by 10 square

Our silica processing 5500 series horizontal belt filter is highly efficient and provides a low maintenance solution for processing mined sand. Our horizontal belt filter provides a filter cake with a moisture level of less than 5% for our sand processing customers including:

• EOG Resources
• Fairmount Minerals
• Mining Consultants
• Mohawk Garnet
• Pattison Brothers Sand Company
• Quality Sand
• U.S. Silica
• Wedron Silica Company

Our rotary vacuum Condisk series of filters are aimed specifically at mineral concentrates such as copper, iron ore, bauxite, lead, molybdenum, and vanadium. This new generation of disc filters is designed for higher rotational speeds and a more efficient filtration cycle. Our Condisk filter is designed with a Compositech Composite Centershaft which is a specialized component designed to provide a solution for customers who use disc filters for processing slurries with a corrosive pH level as low as 0.3.

We are also able to offer our Composite Centershaft as a replacement part for disc filters made by other manufacturers. Our centershaft is made of engineered plastics, pultruded fiberglass reinforced resin, and elastomers made to withstand extremely corrosive environments. This product has a lifespan 8 times that of a standard cast iron centershaft operating in a corrosive environment. In addition to the centershaft, we have many mining customers who use our replacement sectors which are designed specifically to withstand mining and metallurgical processing. Though typically made of stainless steel, for our mining customers we make sectors with a body of engineered plastics.

Our drum filters, which have been engineered to meet application demands for mining and metallurgy processing, are available with several discharge options. The most appropriate drum filter discharge is determined by the specific application for each customer. In clarifying applications, very high filtrate clarity can be achieved with a precoat discharge design. For processing caustic slurries, we offer thermoplastic drum filters which provide dependable vacuum filtration at a substantially lower cost than exotic metals. All components which contact corrosive agents are made of engineered plastics.

In addition to manufacturing our own lines of filters, Compositech also provides replacement parts and performance upgrades for the mining industry aimed at existing installations of disc, drum and horizontal belt filters. Our goal is to offer upgrades to throughput and reliability through our replacement parts. Our parts meet vigorous standards for quality and durability and are designed to offer increased filter performance and lower maintenance costs. Our components meet or beat the quality of the original equipment used by the filter manufacturer.

Frequently Asked Questions

What type of filters are used in mining and metallurgical processing?

Mining and metallurgical operations typically use horizontal belt filters, rotary vacuum disc filters, and drum filters. These are built with corrosion-resistant materials and engineered plastics to handle abrasive, high-tonnage slurries, acidic leach solutions, and caustic tailings while maintaining consistent throughput and filtrate clarity.

What is a mining filter press used for?

A mining filter press dewaters tailings and ore concentrate slurries, separating solids from process liquid for disposal, reuse, or further metal recovery. It reduces moisture content in the filter cake, improves water recycling, and increases overall processing efficiency in high-tonnage mineral operations.

How does a horizontal belt filter work in mining applications?

A horizontal belt filter continuously moves slurry across a permeable belt while vacuum draws liquid through, separating solids from liquid. In mining, it is used for washing filter cake, recovering valuable minerals, and clarifying process water -- all with no tank required and minimal operator attention.

What materials are used in mining filtration equipment for corrosion resistance?

Mining filtration equipment exposed to acidic or caustic slurries typically uses engineered plastics, thermoplastic drum construction, and corrosion-resistant coatings on all wetted components. This extends equipment life significantly compared to standard metal construction and lowers long-term maintenance costs in mineral processing.

Can filtration equipment be upgraded instead of replaced in mining operations?

Yes. Many mining operations upgrade existing disc, drum, or horizontal belt filters with improved replacement parts -- such as sectors, centershafts, and drainage components -- rather than replacing entire systems. This improves throughput and reliability at a lower cost than full equipment replacement.
