80 km away from Sohar province) mine ore bodies. The
samples are named as stockwork, mid and high-grade based
on their copper content. This study aims to attain a detailed
overview of the chemical and mineralogical characteriza-
tion of the ores and conclude beneficiation experiments for
blend sample which represents three different ore zones by
focusing on validation of the developed predictive simula-
tion models by performing locked cycle test. A summary
table of the study scope is shown in Figure 1.
MATERIAL
The received samples were crushed separately by jaw crusher
and roller crusher until the material passed by a 1.14 mm
sieve. The sample P80 size was reduced between 620 µm to
680 µm for different ore zones. Next, the sieved samples
were combined the provided proportions by Mawarid LLC
and divided into 1.5 kg batches for flotation and mineral-
ogical studies. The proportions of the studied samples can
be seen in Table 1. Sample preparation flowsheet can be
seen in Figure 2, and Figure 3 shows the particle size distri-
bution of –1.14 mm of different ore zone samples.
