Evaluation And Production Of Dolime And Magnesia From Rimba Mas Dolomite Perlis
Dolomite deposit of Rimba Mas, Perlis is one of the major, high quality and significant resource in Malaysia with total inferred reserve of 630 million metric tonne, and normally exploited for low-end as grits for agriculture and construction industries. In this research, evaluation for potential...

| description | Dolomite deposit of Rimba Mas, Perlis is one of the major, high quality and significant
resource in Malaysia with total inferred reserve of 630 million metric tonne, and
normally exploited for low-end as grits for agriculture and construction industries. In
this research, evaluation for potential of value-added product development of the
resource for high-end and advanced product applications in higher economic sector
were envisaged and explored especially for calcined and high quality compound of
Magnesia (MgO) production. Geologically, petrographically and chemically indicated
that Rimba Mas indeed a high grade dolomite rock (>99.0%) and often with marginal
impurities (,0.6%). The lime (CaO), Magnesia and LOI (C02) contents are generally
32.78%,20.01% and 46.6% respectively. Generally, dolime (MgO.CaO) of the resource
is absolutely acceptable and possessed a good calcination value, attained at optimum
temperature of about 1000°C@90 minutes soaking time, a low decrepitating «1.00%)
and settling rate. Qualitative and quantitative XRD analyses (using rietveld method)
performed on the similar batch of dolime also show the similar trends, where the total
amount of MgO and Mg(OH)2 components are significantly high about 46.50% with the
lowest CaC03 «6.50%) fraction. Whilst, re-carbonation test have successfully
generated high pure MgO compound. Initial test also proved the possibility of Magnesia
extraction through the modified Pattinson's process route is feasible with the yield over
99.00%, however additional test works and economic evaluation are necessary. |
