A study on floatability of copper using Modified Hallimond Tube

Aimi Noorliyana, H.; Mohd Zaheruddin, Kasmuin; Md. Fazlul, Bari; Sri Asliza, Md Amin; Kamarudin, Hussin, Brig. Jen. Dato' Prof. Dr. (Universiti Malaysia Pahang (UMP), 2009-06-20)

The Floatability of copper on the Modified Hallimond tube depend on lots of parameters such as dosage and types of collector, frother, air flow rate, flotation time, and pH value. All of this parameters give different ...

Study the effect of TIO2 and soaking time to the natural hydroxyapatite properties

Shahrizal, M. H.; Sri Asliza, Md Amin; Mohd Nazree, Derman; Mohd Zaheruddin, Kasmuin (Universiti Sains Malaysia (USM), 2006-05-24)

Natural hydroxyapatite has potential to be used as implant material in biomedical applications. In this study natural HA were obtained from bovine bone by heated and ground into desired size. Dense natural HA were fabricated ...

Study the properties of dense Hydroxyapatite - Extract from cow bone

Sri Asliza, Md Amin; Mohd Zaheruddin, Kasmuin; Shahrizal, H.; Nurul Fazliana, Z. A (Malaysian Institute for Nuclear Technology Research, 2009)

In this study, natural HA were extrated from clean cow bone by treatment with NaOH and heating at high temperature before ground into fine powder. The HA powder were than mixed together with binder for several hours. Dense ...

Preparation and characterization of natural Hydroxyapatite from bovine bone

Shahrizal, M. H.; Sri Asliza, Md Amin; Mohd Nazree, Derman; Mohd Zaheruddin, Kasmuin (Universiti Sains Malaysia (USM), 2008-06-18)

The purpose of this study was to prepare and characterize Hydroxyapatite from natural source. Hydroxyapatite fine powder with average size particle of 10.324 um had been prepared by heating bovine bone at temperature 800°C ...
