The interactive effect of depressant type and dosage with frother dosage in the flotation of a PGE ore [PDF]
, 2005 The valuable components of the platinum group element (PGE) bearing ores of the Bushveld complex in South Africa constitute between 1 % and as little as 0.1 % of the total mass. In the processing of these ores by flotation, the naturally hydrophobic talc

Synthesis of Oleic Acid Derivatives as Pour Point Depressant (PPD)
Jurnal Kimia Sains dan AplikasiCrude oil is widely used worldwide as an energy source in various fields. Over the years, crude oil production has decreased due to one major problem that continues to occur, namely wax deposition. Wax deposits tend to occur due to the composition of the

The Effect of Pour Point Depressant on the Flow Behavior of Crude Oils
, 2014 In this research, pour point and rheological experiments were carried out on three different crude oils those doped with pour point depressant. It was observed that when the amount of pour point depressant was increased from 500 to 2,000 ppm, pour points

Pediatric Blood &Cancer, EarlyView.ABSTRACT Rates of cancer among adolescents and young adults (AYA), age 15–39 years, are increasing. Consequently, radiation oncologists are treating more AYAs who have diagnoses spanning both pediatric and adult practices. Compared to pediatric and older adult patients, AYAs face a unique set of challenges.
