(PDF) Screening and Sieve Analysis
The screening was done using an industrial screen and the sieving was done using laboratory Tyler sieves. The initial mass of the ore manually fed to the screen was 11.965 kg. However, the total mass of the respective launders (particles <8mm, <10mm, <22mm, and >22mm) after screening was 11.64 kg. The losses are mainly due to blinding, type …
