Samples of copper tailings were collected from the overflow and underflow streams of the primary hydrocyclone at the processing plant discussed in Section 21The d90s of these samples were 637 μ m and 279 μ m respectively and the particle size distributions of each can be found in Fig 1The samples were obtained as slurry, which was subsequently dried and the two sizes combined in Expertise in safe and efficient tailings rehandling Read more With our proven track record in alluvial and marinemining, and tailings rehandling projects, we provide a suite of services focused on safe, efficient and effective operations to unlock the potential of these mining legaciesTailings advisory services Royal IHC East Africa Metals Inc (TSXV: EAM) (FSE: EA1) ("East Africa" or the "Company") is pleased to announce that further to its press release dated January 27, 2021, the Company has received the East Africa Announces Tailings Reprocessing Designer Tailings is a science and evidencebased methodology for generating alternate operating options for the desired environmental outcomes Through a detailed knowledge of the ore properties and processing conditions, and a mathematical simulation of the processing operations, Designer Tailings can predict the likely nature of the tailings generated, potential environmental Designer Tailings: A Lifecycle Approach to Tailings As an owner of the Whitehorse Copper Tailings, it’s true substantial opportunity and value exists, leading the next generation of Value from Waste involves companies like , Groundtrax Environmental etc which are leading the way through this game changing frontier which will have far reaching benefits and surely deserves the recognition the Canadian Mining Journal has providedCreating value from waste Canadian Mining
