Israel Chemicals has agreed to sell its 50 percent stake in water desalination firm IDE Technologies for about $180 million, a leading Israeli financial news website reported on Tuesday.

Israel Chemicals (ICL), a top global supplier of potash, and IDE both declined to comment.

IDE, which has built major desalination plants in the United States, Israel, India and China, is jointly owned by ICL and Israeli conglomerate Delek Group.
