Community project restores dignity to girls


Since several  years, Imerys Refractory Minerals implements education programs, supports agricultural cooperatives and modernizes infrastructures to improve life standards of its employee’s communities.

Late 2015 Imerys South Africa started partnership with The Peace Agency  to fund  locally produced Subz Pads packs of washable sanitary pads and underwear to fight against absenteeism and drop-outs of girls in high school living close to Imerys Annesley mine in the Limpopo province. It appears that 60 %+ of girls in South Africa miss 18 months (out of 5 years) of high school due to not having access to sanitary products.

Xolisa Mvinjelwa, Executive Director for Ethics & Transformation, explains “The villages around our mine are made up of poor communities with high unemployment and low levels of education. Families depend on grants and parents are unable to afford these sanitary pads.”

In 2016 the initiative was repeated and extended to other schools. Schools’ principals and staff observe a lower rate of absenteeism and drop-outs. Furthermore they feel that the girls have more confidence in themselves which enhances the level of creativity in the classroom.

New Face Coat Material for Investment Casting Molds

Imerys Refractory Minerals for foundry applications in collaboration with CARRD, Imerys R&D center for refractories & abrasives, developed a new solution for face coat material.

The Treibacher Alodur WRG IC ESR , a synthetic material  based on fused alumina, is the ideal alternative to zircon for face coat applications.

Our solution was introduced during WCIC, World Conference of Investment Casting held in Paris in April 2016 by Dr Thomas Krumrei , CARRD R&D engineer and expert of Investment Casting technology.

Specially modified fused alumina (WRG IC ESR) exhibits outstanding properties, when it comes to heat resistance and chemical stability. These properties allow casters to avoid vitrification and migration of alloying elements into the ceramic mold. Furthermore, its high heat and deformation resistance is one key element to producing castings with extremely tight tolerances (for e.g. turbo charger wheels).

Another key advantage of modified fused alumina is its excellent compatibility with standard Na-stabilized binders. Even after 10 months test-runs, slurries show no signs of changes in optical, pH, or viscosity values.

The lack of natural impurities and variations, especially in face coat materials is definitely one of the biggest advantages of this new primary coat generation. Use of this material allows for irregular appearance of defects in castings to be reduced to a minimum….

1st Imerys Refractory Minerals Safety Day

First Imerys Refractory Minerals Safety Day

At Imerys Refractory Minerals just as throughout the Imerys group, safety is our number one priority. Imerys develops a proactive safety and health culture by implementing the three pillars of the Imerys Safety System: compliance, continuous improvement and communication. It is structured along the following lines: clearly defined audit protocols, regular audits, a global training plan, safety training based on a behavior-based model, an accident analysis program and a serious accident prevention plan, as well as events designed to strengthen safety culture.

Over the past years, various actions were taken to modernize production sites and machinery, and important means were put on improvement of security awareness throughout the Imerys Refractory Minerals staff. Whether high or medium level managers or workers on the production sites in France, the UK, the USA, South Africa and China, everybody took action for best security within the division.

November 24th was 2016 Safety Day at Imerys Refractory Minerals. Each production site interrupted its activity for half a day bringing together local staffs to strengthen safety awareness. Time was dedicated to align with the division safety targets, actions and results. Teams were given the opportunity to discuss their local security approach and behavior change thanks to the “Take 5” program for example. “Take 5” is a pre-task risk assessment and reduction tool helping drive safety awareness to all employees. It was launched in 2014. Early this year “Serious7” went life. It is a new protocol  for forklift safety helping site managers to review specific issues such as technical deficiencies or regular maintenance matters.

Randalusite™ Premium: purest andalusite grade ever

Imerys Refractory Minerals launched a new product called Randalusite™ Premium, which is the highest quality andalusite available on the market. Indeed,  Randalusite™ Premium is the purest product in terms of chemical and  mineral composition.  It allows refractory producers to use andalusite applications where high creep resistance are mandatory. A study comparing the perfor­mance of different types of andalusite raw materials was presented during the 2016 Aachen Refractory Colloquium. In this study, a broad range of andalusite was characterised, in particular regarding chemical and mineralogical composition. Specific attention was given to the distribution of impurities across the different size fractions.

Refractory bricks and castables were produced from each type of andalusite on a laboratory scale in order to establish a correlation between the raw material purity and the refractory performance. Thermo-mechanical properties such as Refractoriness under Load (RuL) and Creep in Compression (CiC) were investigated, with a particular focus on the impact of impurity level, its enrichment in the matrix and its influence on the microstructure.

The outcome of the study allowed Imerys Refractory Minerals to launch Randalusite™ Premium.  Its alkalis are lower than 0.35% and its alumina higher than 60%. It is obtained by advanced processing designed for high performance bricks & castables thus opening doors to new applications for andalusite based refractory solutions.

Imery Refractory Minerals - Metakaolin under microscope

Imery Refractory Minerals – Metakaolin under microscope

July 5th, Cyrille Deteuf,  Imerys’ Metakaolin specialist provided a review on  Metakaolin  for Geopolymer at the occasion of the 2016 GeopolymerCamp.

The Geopolymer Institute based in French Picardie organizes the annual GeopolymerCamp since 2009. This event is an ad-hoc gathering born from the desire to share and learn in an open environment.

The camp is neither a conference, nor a congress. It is a casual, informal meeting between anyone who has something to share in the field of polymers, and anyone with the desire to learn, to interact, and to network.

Innovation is worthwhile!

AImerys Refractory Minerals for Foundry application team at WCIC 2016pproximately 500 people attended the 14th World Conference for Investment Casting which ended in Paris April 19th.  Imerys Refractory Minerals for Foundry Application took this opportunity to present its new organization and 4 new products.

GreenShell+ is a combination of ceramic materials preventing the formation of crystalline silica throughout the casting process, reducing significantly the risk of exposure to hazardous dust for foundry operators and allowing the easy disposal of the shell.

Teco-Sil B1+ and Teco-Sil Hybrid +, both allow reducing the number of layers and to speed up the shell building process. The first is a fused silica-based blend and the second an aluminosilicate-amorphous silica blend.

Treibacher Alodur WRG IC ESR is a modified aluminium-oxide flour designed as a primary coat for casting and Ni-based super alloys. Its easy shell removal quality facilitates casting cleaning.

Imerys Refractory Minerals for Foundry Applications would like to thank its visitors for their interest, feedback and support, which is essential to move forward in the foundry industry as pointed out by Ing. Franz Bernasconi when receiving the 2016 EICF Life achievement award.
