This study covers raw fresh milk of cow, goat and camel (farm and pasture-reared),in addition to two brands of commercial milk samples, liquid milk of powder origin and drinking yoghurt samples.  Camel milk showed a relatively lower pH range (6.15 - 6.46) compared cow, goat and commercial milk. The pH of drinking yoghurt was found (4.35 - 4.47).Microwave digestion, was selected followed by mineral analysis using Inductively Coupled Plasma-Optical Emission Spectrometry.  Micro minerals; Cd, Cr, Cu, Fe, Mn and Pb, ranged from not detected to 23.4+0.52mg/L for Fe while Sr (0.32+0.005 – 2.51+0.043 mg/L) and Zn (1.58+0.01 – 8.91+0.14 mg/L) in all milk samples.
