every 1.5m and washed for tin ore. The tin would then be weighed, dried and kept in plastic bags (Figure 3). The type of soil for every layer would also be recorded. OVERBURDEN STRIPPING The removal of non ore bearing earth or overburden could be done either by dry or wet stripping. In dry stripping, the earth would be excavated by
This study aims to conduct mineralogical characterization and determine the refractoriness of gold ore from Eastern Coast of Peninsular Malaysia. Elements presence in the sample were investigated using X-ray fluorescence (XRF) analysis while X-ray diffraction (XRD) method was used for the identification of mineral phases.

gold mineralization zones occur within the medium to high magnetic area, where there is no indication of basic intrusives (Geological Survey Malaysia, 1982. The vein type deposits are usually shown by low magnetic and low radiometric areas. Structural studies show that there are
The use of dry-type transformers has proved to be suc-cessful in a range of applications. Such equipment is often used in medium-voltage power grids in industrial plants and in the marine and civil sectors, such as in subway networks. Deciding factors for the use of dry-type trans-formers include low-maintenance operation and reduced fire risk.
Gold in refractory sulfide ores occurs as fine inclusions or in solid solution typically within pyrite, marcasite, and arsenopyrite grains. In this type of ore, because the gold is encapsulated, the interaction with cyanide to form the soluble metal complex is inhibited (Marsden and House, 2006, La Brooy et al., 1994).
Based on the field relationships, ore microscopy and geochemical data analysis, there are two main gold mineralization type in the southern part of Ulu Sokor gold deposit, namely (1) Gold …

Our high-capacity spiral separator (the HX series) provides a per-start tonnage rating of 5 to 9 tph, depending on the mineral type, and is especially suited for the treatment of low-grade ore, where large tonnages are processed.
Gold is chemically inert under most low-temperature weathering conditions. However, it becomes mobile in the presence of certain complexing ligands in soil and groundwater (Gray et al., 1992a, Gray et al., 1992b), depending on the geomorphological setting, weathering environments and climatic conditions (Butt, 1998). Gold forms complexes with ...
