Langer Heinrich Uranium - Namibia
The company was awarded to design and supply two 35m counter current decantation (CCD) thickeners for Namibian uranium mine, Langer Heinrich for its Phase 3 expansion project.

The tanks are due to leave the workshop for delivery in the next few of weeks. This is Roytec's first thickener contract with the client, although it did previously supply the fixed bed ion exchange circuit and the large volume segmented tanks for the same project. The project consists of the supply of the thickener tanks, hydraulically driven high torque drive mechanisms, rake arms, rake blades, high rate feedwell, agitated feed tanks and pumped feed dilution mechanism.

Optimum Colliery - South Africa
Also recent, Roytec SA is supplying a 4m² Vacuum Belt Filter (VBF) to Keyplan for the company's Optimum Colliery high recovery desalination process (HiPRO) plant for Acid Mine Drainage (AMD). AMD are waters arising from gold, coal, uranium and platinum mine operations and is a major threat to the environment.

The VBF will be used to dewater the precipitated gypsum from the treatment process prior to final recovery. The plant is currently under construction in the Middelburg area with commissioning expected in the later part of 2010.






February 2010
BBBEE Rating
We have for several years now implemented a Black Economic Empowerment Policy to promote entrepreneurial communities and give emerging businesses access to mainstream business opportunities. We concentrate our empowerment efforts on suppliers of goods and services in the manufacturing, construction and consumables sectors. Roymec Technologies management is actively committed to enforcing this policy and provides both input and resources into this endeavor

More recently we have completed a stringent internal self audit process for which we have scored within the current BBBEE requirements as set by the Mining Charter and the Minerals and Petroleum Resources Act.

To formalize the rating level we have subsequently employed an independent transformation/rating company to assist with further improving our rating score and processes within the next financial year. We are looking to make improvements in areas such as socio-economic, enterprise and skills development.



September 2009
Segmented Tanks
Roymec highlights the supply of the large volume segmented tanks for the Langer Heinrich Uranium project in Namibia. The benefits for the segmented tank concept are particular for remote sites in that they are extremely cost effective, delivered to site in pre-packed pallets and are installed in a third of the time compared to welded tanks. In addition cranage and scaffolding are not necessary since the tanks are light weight and can be picked up by a telescopic loader.

Skorpion Zinc - Namibia
The Skorpion Zinc mine is located some 25 km North of Rosh Pinah in South West Namibia. The mine is part of Anglo American’s Base Metals division and complies with the stringent requirements for all health, safety and environmental issues. The plant has been in operation since 2002 and produces 150,000 tpa of special high grade (99.995%) zinc metal.

“The primary purpose of this particular project was to clarify the pregnant leach solution to enable production of the highest quality zinc metal thereby commanding a premium on the world market” says Skorpion Zinc’s project manager .Jacques Kruger.

PLS clarification is a perennial problem on most base metal recovery plants with operators employing various methods to aid solution clarification. Suspended solids in the PLS forms crud and affects phase separation in solvent extraction plants and is detrimental to the final metal plating process in electrowinning.




July 2009
Skorpion Zinc - Namibia
Kathy Sole, Anglo Research Project Manager for this pilot trials said, “The tests demonstrated conclusively that the Roymec pilot PBC could successfully maintain the PLS suspended solids to within the required design specifications."





June 2009
Sasol Synfuels -Secunda - South Africa
Design, supply, manufacturing, Supervision of installation and commissioning of four off Decanter drive mechanisms incorporating hazardous area classification zone 2 controls and mechanical equipment.

The project involved the modernisation of the existing drives on the site and comprised:
Electric drive-head with integral rake lifting mechanism.
Local lift instrumentation.
Local control panel.

The new drive stations were retrofitted onto the existing decanter bridges and available rakes, feedwell and driveshaft and offered significant cost benefits. The units were fully assembled and shop tested.

Tenke Fungurume - DRC
Roymec supplied all off the Pinned Bed Clarifiers, the SX Dual Media Filters and Flocculant and Reagent Plants for the Tenke Fungurume Project in the Democratic Republic of Congo owned by Freeport-McMoRan.





June 2009
Kayelekera Uranium - Malawi
Roymec supplied the Ion Exchange – Elution circuit to the project, comprising the resin eduction system, elution columns, pumps, piping and instrumentation.





June 2009
Skorpion Zinc - Namibia
Skorpion Zinc has not been able to reduce the PLS suspended solids to the stringent specification levels required for zinc solvent extraction. The mine has trialed numerous clarification technologies since start up including sand filters, conventional large diameter clarifiers, floating media filters, without success. During extensive PBC trials that were run and supported by Anglo American Research using Roymec’s pilot PBC unit, feed to the unit ran at between 50 – 250 ppm. Kathy Sole, Anglo Research Project Manager for this pilot trials said, “The tests demonstrated conclusively that the Roymec pilot PBC could successfully maintain the PLS suspended solids to within the required design specifications.




June 2009
Tenke Fungurume - DRC
Roymec supplied all off the Pinned Bed Clarifiers, the SX Dual Media Filters and Flocculant and Reagent Plants for the Tenke Fungurume Project in the Democratic Republic of Congo owned by Freeport-McMoRan. Tenke Fungurume could be the largest, undeveloped, high-grade copper/cobalt project in the world, according to company president and CEO Richard Adkerson, which has budgeted up too $900-million in capital expenditure to complete the project. The current project, which will have its first full year of output in 2010, will produce an average of 250-million pounds of copper and 18-million pounds of cobalt a year.




June 2009
Kayelekera Uranium - Malawi
The Kayelekera Uranium Deposit is located in Northern Malawi in Southern Africa. The project is held by Paladin Africa Ltd, a Malawi registered company and a wholly-owned subsidiary of Paladin Energy Ltd. Paladin is listed on the Australian Toronto stock exchanges. The Malawi project has proven reserves of 11.5Mt of contained uranium oxide. It would be Paladin's second-largest uranium mine and its second in Africa. Roymec supplied the Ion Exchange – Elution circuit to the project, comprising the resin eduction system, elution columns, pumps, piping and instrumentation.
