Soil Air Carbon Dioxide and Oxygen Measurements as an Aid to Exploration for Concealed Sulphide Mineralisation in South Australia - a Practical AssessmentBy Morris B. J
Soil air samples taken from the top one metre of the soil profile, were measured for C02 and 02 using portable field analysers at a number of sites of known sulphide mineralisation in South Australia.

The interaction between slag and MgO refractory at conditions relevant to nickel laterite ore smeltingBy A D. Pradana, D R. Pradana, Y H. Putra, Z Zulhan, T Hidayat
The high temperature processing of nickel laterite ore is currently dominated by the Rotary Kiln- Electric Furnace (RKEF) technology. The ratio of SiO2/MgO (S/M) in the ore is one of the critical para

Determining the Open Pit to Underground Transition – a New MethodBy P A. Grossman, J H. Rubinstein, M Brazil, D Whittle
Many ore reserves are harvested by a combination of open pit and underground mining methods. In these cases, there is often material that could be mined by either method, and a choice has to be made.

The Effects of Ore Type and Bed Depth on Sinter Production and QualityBy J Manuel, L Lu
Increasing bed depth is one of the main options sinter plants consider to increase production, since it is an incremental improvement and less expensive compared with a new plant. To maximise the bene

The Practice of Engineering Geology in the Planning and Construction of the City of Canberra, A.C.T., AustraliaBy de Vries D, Wilson EG, Henderson GAM, Carter EK
Canberra is a planned city in which the natural environment, rather than existing development and land tenure, has until recent times at least, imposed the major constraints to development. Even r
