The scope of this paper and presentation is to address the properties and benefits of the alkaline cyanide-free zinc deposit as a base coating for paint and powder coating applications. The deposition structure and process characteristics for alkaline cyanide-free zinc plating will be evaluated and compared to acid chloride zinc plating, zinc phosphating and iron phosphating. Salt spray testing...

alteration was ohserved along minor subsidiary faults in the northwest and northeast parts of Iron Range Mountain. The main Iron Range deposit consists of the segment of the ault containing the richest iron mineralization and underlies the northern half of the ridge which makes up Iron Range Mountain. This area extends northward onto the Grassy Mountain sheet (82FB). The area of m...

introduction iron-apatite ore deposits well known as kiruna iron type formed in association with calc-alkaline volcanism from proterozoic to tertiary (hitzman et al., 1992). liquid immiscibility in an igneous system was proposed to explain the formation of the iron oxides accompanying apatite in mineralized zones (förster and jafarzadeh, 1994; daliran, 1999). the mode of ore formation however, ...

This work aims at figuring out the spatial relationships between the geophysical and geological models in a case study pertaining to copper-sulfide mineralization through an integrated 3D analysis of favorable target. The Ghalandar Skarn-Porphyry Cu Deposit, which is located in NW Iran, is selected for this research work. Three geophysical surveys of direct current electrical resistivity and in...

The grossular–andradite garnet is an ideal mineral for indicating the formation age of skarn, which also pretends to constrain skarn processes because its higher REE (rare earth elements) content. Tongshanling deposit a medium-sized reduced Cu–W–Pb–Zn associated with highly evolved I-type granodiorite intrusion in Nanling metallogenic belt, South China. Different assemblages, microscopic charac...

When a steel pilot plant reactor was emptied, and left exposed to the humid summer atmosphere over a weekend, a heavy corrosion deposit formed on the inner surface. Because the process stream contained triflic acid (trifluoromethanesulfonic acid, CF3SO3H), the engineer wanted to determine whether the deposit contained triflate(s) [1]. The brown deposit was ground in a mortar and pestle. The maj...

The Pandian deposit is a newly discovered contact metasomatic skarn magnetite found in the Cainozoic super-thick overburden on northwest margin of Luxi Uplift (LXU). Presently, horizontal scale delineated by potential field (gravity and magnetic method) has shown giant for ore deposits, mapping ore-controlling structures vertical becomes primary task metallogenic prediction. In our study, wide-...

kajal kaolin deposit is located ~20 km northwest of hashtjin, ardebil province. field evidence and laboratory investigations show that the deposit is an alteration product of ignimbrites, tuffs, and trachy-andesites of eocene age. according to mineralogical data, the major rock-forming minerals include kaolinite, montmorillonite, polygorskite, orthoclase, zeolite (stilbite), quartz, and chalced...

This study presents rock slab and thin section reflection mapping, element mapping by Micro-XRF (μ-XRF) analysis, in situ cassiterite U-Pb laser ablation-inductively coupled plasma mass spectrometer (LA-ICP-MS) ages of the Xinlu Sn-Zn deposit, Nanling Sn-W belt, South China. The new results provided constraints on age processes Sn mineralization thus further discussed role Paleo-Pacific plate f...
