    Philippine miners press government to remove large-scale

    The removal of the small-scale ban may be in direct response to the significant illegal small-scale mining in the country; the government estimates that 60%-70% of small-scale miners in the country operate illegally, endangering workers, damaging local environments, and mining seams that could be used by legitimate companies.

    removal; Large scale mining involves a large company with many workers. These are also localized at one or two sites. Small scale mining involves a group of traveling men, usually about 5-8, who migrate from one mining site to another. This type of mining tends to be more destructive to the environment because of the area of land covered. It also causes more social problems because small scale

    Descaling Metallurgical Processes

    I am concerned with the thermal scale that is created on 2-1/4CR pipe like A335 P22 that operates in the creep range (1000 F), I recommend that the pipe surface be "hot popped" using a cutting torch. The operator MUST sweep the torch over the surface at an angle to heat up the scale. The scale will then "pop" off. Then, I recommend going back with a grinder to remove remaining scale. Finally

    Large Scale Miners Clean Mining (For A Richer Earth)

    Clean Mining can provide large-scale miners with a safer, more responsible alternative to cyanide. This potentially reduces ongoing compliance costs as well as additional costs relating to end-of-mine rehabilitation liabilities. The use of cyanide is an industry standard for large-scale mining companies who understand the risks and accept the liabilities. Many miners have a good environmental

    Mining — Belt-Way Scales

    There are many different mining processes where a scale is crucial. Scales are required to measure raw material drawn out of the pit. From there it may get sent to a crusher (or two) to convert the material to the proper size. Scales are also required on the feed conveyors to secondary and tertiary crushers. After the crushers, the material is typically sent through a screener and delivered as
