Solutions for Non-Ferrous Metal Smelters and Refiners

Overview

Clyde Materials Handling (CMH) has used its technology, expertise and domain knowledge to power pioneering solutions globally across the copper industry.

CMH is recognised as the leading global provider of pneumatic conveying and injection solutions across bulk handling applications.

Thorugh the utilisation of its Non-Ferrous Metals Market Team, CMH are working closely with producers to apply existing solutions across the non-ferrous metals market.

This market-based team are also applying CMH technologies extensively to bring new solutions to smelters and refiners.

Over the last decade, CMH have pioneered solutions for operaters across many non-ferrous metals. Initially active in the copper industry, CMH have successfully diversified their solutions to the lead, zinc, platinum and aluminium industries.

The non-ferrous industry has many similar transportation needs where CMH equipment is ideally suited. CMH can provide operators in the non-ferrous market with the following benefits:

Specialists in low wear, low power dense phase conveying of abrasive materials
Durable, reliable systems with high availability, low maintenance
Lead supplier of pulseless furnace injection equipment, allowing enhanced distribution and process stability
Lead supplier of bulk handling valves with acknowledged performance in non-ferrous industry
Track record in partnering users to provide solutions


Clyde Built Solutions

CMH's 'Clyde Built' solutions are known for their quality, durability, reliability and exceptional performance. These traits are of great importance due to the abrasive nature of copper concentrate and the exertions this, and other substances such as silica, reverts, matte, metallurgical dust and carbon, can place on the systems supporting its use.

The smelting process lies at the heart of the copper producers operation - to perform optimally a consistent, reliable and controllable feed of copper concentrate needs to be generated in order to achieve consistent high production levels of metal and enable the smelter and the other downstream processes to operate at a steady, optimum rate.

CMH has developed a unique copper concentrate handling and injection system that can significantly enhance the output from a copper smelting process. This solution can be utilised on a bath or flash smelter, blast or flash furnace, flash converter, Noranda converter, Codelco CT converter, Pierce Smith converter, and other secondary processes for conveying or injecting dusts, additives, coal and other carbons, fuels or fluxes.

Clyde's solutions have the ability to transport copper concentrate, or any other substances associated with the smelting process, in an unrestricted, controlled and continuous manner at low velocity, consuming low volumes of compressed air. The result is the creation of a solution that absorbs a minimal amount power, causes less wear on system components and pipelines, and therefore, reduces maintenance costs and increases system availability, reliability and production.

Clyde solutions have the ability to evenly and accurately inject the material into the smelters using specially designed distribution mechanisms. This process is complemented by a unique lance design, which is able to effectively disperse the material within the liquid metal bath of the smelter, furnace or converter.

The solution is further enhanced through the use of Clyde's Dome Valve, widely regarded as the best material handling valve in the world. The Dome Valve has the ability to cut through static or moving columns of material through the use of its innovative inflatable seal mechanism, ensuring that a consistent pressure tight seal is created when the valve is in the closed position, but in the open position it provides an unrestricted full bore opening for the best product flow characteristics possible.

The Clyde Dome Valve is recognised as a low maintenance, long life solution that can last at least 1 million cycles between maintenance inspections.

CMH's 'Clyde Built' solutions have a proven track record in generating rapid returns within the copper industry and has added the following benefits to its clients:

This results in the production of a system that generates the following benefits:

Sustainable economic advantages
Increased system availability - Clyde solutions have provided 15 days more production per annum
Greater accurate concentrate feed control +_5% to +_1%
Stabilisation of process control
Reduced carryover of dust to acid plant and gas cleaning plant
Reduced turbulence and refractory wear
Decreased dust production potential

 

This results in the production of a system that:

Increases copper output due to even and accurate distribution and smelter utilisation - Clyde has helped achieved a 30% increase in output through the use of its technology
Which, in turn, results in increased productivity and profit
Reduces material waste and dust release as the process is completely enclosed, helping to recuce downtime
Environmentally sound - able to prevent exposure to high-risk substances such as arsenic dust and silica
Reduction in maintenance costs - 'Clyde Built' systems use low velocity conveying with little wear and tear on parts, ensuring a level level of system availability and performance
Is flexible to integrate with existing smelter infrastructure, complementing not replacing previous investments
Offers excellent process control
Effectively disperses material within the liquid bath by utilising a uniquely designed lance - the 'Clyde Built' lance has a greater life expectancy of standard lances, which is able to increase system availability, reliability and performance
