Open pit mines
are used extensively in "hard rock" mining for
ores such as metal ores, copper, gold and many
is the process to extract precious metals like
gold, silver, copper and uranium from their ore
by placing them on a pad (a base) in a heap and
sprinkling a leaching solvent, such as cyanide
or acids, over the heap. This process dissolves
the metals and they collect at the bottom of the
pad. The metal is then further processed.
Certa-Lok Yelomine is manufactured from a specially
formulated PVC compound that contains impact modifiers
and UV (Ultraviolet) inhibitors. These modifiers
and inhibitors provide higher impact strength over
an extended period of time and allow Certa-Lok
Yelomine to be used in above-ground, exposed applications
as well as underground or buried applications.
Industries 900 Series Tornado Filter is an inline,
self-cleaning water filter, designed for Well Water
and Surface Water Filtration applications.
The key to the Tornado Filters success is the
combination of an Entrance Nozzle Plate, Velocity
Tube, High Velocities down the Length of the
and Reduced Flow

From the pivot point to the last span, a Valley center pivot is engineered, constructed and field-tested to handle any operating stresses your machine
may experience. Valley structures stand up to the toughest loads produced by rough terrain, deep furrows and long-span machines. No wonder Valley center
pivots command the highest resale value in the industry.
Irrigating your square, rectangular, and oddly shaped fields isn't a problem! Valley® linear machines offer you great advantages not found in other farm irrigation methods - advantages that can increase your field's potential and your profitability.
Your center pivot irrigation technology has saved you water and increased your yields, but what about those field corners and areas around existing structures and trees? Valley® corners, Benders, and DropSpan™ can solve these challenges by picking up those missed corners and that non-irrigated land.
When a center
pivot or a lateral move system isn't what you need,
you can be sure we have a specialty system that
meets every one of your requirements. Whether your
field is small, demands frequent light applications
or has an obstacle or two, we have just the right
system for you.
