In this study, upgrading of flotation silica/glass sand concentrate (clear flat glass quality), sized 0.600 +/- 0.106 mm, from Camis Mining Company (Mersin, Turkey) was investigated applying amine flotation. In the experimental work; Armac-C, Armac-T, Armoflote-64, Armoflote-586, Armoflotc-565 and Armoflote-P were used as cationic collectors keeping other flotation conditions constant. Armoflote-565 gave the best results as an effective collector since the Fe(2)O(3) content was reduced from 0.098-0.03% with 70.4% iron removal efficiency after applying two cleaning stages of amine (Armoflote-565, 800 g/t) flotation onto the glass sand concentrate (clear flat glass quality) treated traditionally in the plant. The upgraded silica concentrate can be utilized as for manufacturing the household white glass (Fe(2)O(3) <= 0.05%). The floated product (the tailings of the amine flotation) can be a raw material for production of some titanium concentrates due to its TiO(2) content.
