MODULAR PROCESS SOLUTIONS

Utilizing our experienced team of engineering professionals, Plants and operations are designed to minimize construction Sepro designs and builds modular and mobile processing time, minimize expenses, and to be easily serviceable in plants for a wide range of minerals. We create solutions remote locations. Commissioning time on site is decreased using an array of processing techniques that encompasses by thorough shop testing of the major components and numerous unit process operations. Complete plants are sub-assemblies. assembled utilizing Sepro manufactured equipment, but are All of Sepro’s plants are designed to international processing optionally designed to accommodate innovative solutions and safety standards and can easily be containerized, shipped and equipment from a wide variety of vendors and and reassembled, even in the most remote locations in sub-contractors. the world! Sepro’s engineering team creates versatile and expertly Process testing is critical to the success of any plant, and designed process solutions to match even the most difficult our partnership with a full service metallurgical laboratory specification. All modular plants may include primary and provides Sepro the opportunity to fine tune the process secondary crushing, screening, agglomeration, washing and to suit the ore type. scrubbing, dense medium separation, grinding, gravity concentration, floatation and leaching.

PROCESS APPLICATIONS SEPRO MOBILE PLANTS

Sepro is able to provide customized solutions based around its wide Designed to allow the rapid deployment of a complete plant, range of equipment. Examples include, but are not limited to: Sepro Mobile Mill systems are ideal for smaller tonnage

■ Precious metal recovery operations and / or mining operations with short mine life. ■ Crushing and screening systems Easily re-locatable, the main process equipment is mounted ■ Heap leach agglomeration and conveying systems on road transportable custom built trailer assemblies. These ■ Gravity recovery systems for tin/tungsten/tantalum plants require minimal site civil works. Mobile plants can be ■ Construction aggregate washing and classification designed to encompass a wide variety of process options ■ Nickel laterite slurry prep plants from crushing through to the final concentrate collection. KEY ADVANTAGES SEPRO MODULAR OR SKID MOUNTED ■ Designed to suit your process requirements ■ High quality modular construction Custom modular plants are engineered around structural ■ Proven reliability of Sepro equipment used elements that are simple and easy to erect on site and ■ Modularized single source supply reduces costs minimize civil and infrastructure costs. These plants can ■ Easy to ship globally be designed with larger equipment for higher tonnage ■ Easy to reassemble and commission applications than that of the Sepro Mobile Plants. ■ Designed to have minimal civil work requirements

SEPRO STANDARD MODULAR PLANT DESIGNS

Sepro offers several package options as standard plants. These plants are normally designed around a single recovery or process option such as dense medium separation or gravity concentration. Sepro maintains critical components in stock for quick delivery. MODULAR PROCESS SOLUTIONS
