Abstract This study is concerned with the beneficiation by flotation of carbonate‐rich phosphate rock from the Al‐Jalamid region of northern Saudi Arabia. Flotation of carbonate‐rich phosphate rock has been the subject of intensive research in recent years due to the depletion of deposits rich in silica. A flotation method called ‘short conditioning’ has been defined by the authors for the Al‐Jalamid rock. The optimization parameters are identified and optimum conditions are found for the highest CaO separation efficiency from the phosphate concentrate. The most important optimization parameters investigated were pulp density, pH of the pulp, collector quantity, depressor quantity and flotation time. The optimum conditions determined from the experimental work are: pulp density: 10.61% solid (w/w); pH of the pulp: 6.47; collector quantity: 1.64 g kg −1 of rock; depressor quantity: 20.36 g kg −1 of rock; and flotation time: 3.03 minutes.
