Quality    

  TGM has a well-established Quality Assurance system with a complete sophisticated laboratory at the factory premises that ensures consistent quality of the product. Well-trained master graduates of geology and Chemistry function round the clock to ascertain the quality of the product. As per ISO standard the following tests are carried out on every sample collected.


 
Mineral composition : To check percentage of Minerals
Sieve Analysis : To check grain size
Chloride Content : To check free chloride content
Conductivity : To check electrical conductivity


 
Apart from the testing of Garnet, periodic inspection and quality compliance is monitored for all incoming like packing materials, stainless steel meshes, water used for washing etc., are also tested.
