Copper (Cu) is an essential metal used in various industrial fields such as electric wire, copper products and casting. In the Cu production process, Cu ore is concentrated to Cu (Cu 30 mass%) by mining and mineral processing and the Cu concentrate carried out to Cu refining process. Numerous researches have been investigated the floatation method which is widely used technique in mineral processing. The flotation separation process of chalcopyrite and pyrite which are combined with sodium humate and lime was examined [1]. The concentration of the copper ore from porphyry copper ore was examined using N-propyl N-ethoxy carbonyl thiourea (PECTU) as a frother [2]. Muganda et al investigated the effect of particle diameter and contact angle on the flotation of chalcopyrite in a laboratory batch flotation cell [3]. The influence of different water quality on froth stability and valuable mineral recovery in the flotation of a borate salt ore was investigated by Peng and Bradshaw [4]. The effect of iron, copper, and cadmium on the flotation of a mock lead was also investigated [5]. Many researchers have studied the flotation separation process and they reported the effect of many factors on the froth flotation, but there are a few reports on the flotation in seawater. Nowadays, it is very important to develop sustainable technologies in order to improve water conservation management and to reduce water consumption because most mineral processing requires high water use. Therefore an idea on the use of seawater instead of fresh water in froth flotation is considered as the water source for mineral processing. In some mining, practice of flotation has been made using seawater [6]. Buffering the seawater, hard pH and difficultly to maintain the bubble on surface of liquid are main problems when use seawater in mining operation. Furthermore, it is difficult to understand that mechanism. In this study, we investigated the effect of seawater quality on the flotation of copper ore due to demanding requirements on water conservation management and development of the flotation process. Bubble formation in froth flotation with fresh water and sea water was also observed, respectively. The improvement of Cu recovery from Cu sulfide ore by flotation and floatation behavior of mineral particles as well as generation of bubbles in fresh water and seawater flotation were discussed in this paper.
