The problem with asbestos rock reduction is, how do you crush something… soft. Complicated operating conditions and the type of rock involved made it clear that a specially designed jaw crusher would be needed. Our help was asked. The experience and the ability of Birdsboro’s engineers to grasp and quickly solve unusual Crushing problems enabled us to present […]

Laboratory Balance The Laboratory Pulp Balance illustrated here is very useful for measuring small quantities of reagents and for general laboratory work. It is furnished in capacities from 100 grams to 3,000 grams. Sensitivity varies from 1 mg. on the smaller sizes to 10 mg. on the large sizes. This balance can be supplied either […]
Acid Rock Drainage as a concern and part of all metals and mining operations. ARD is often mislabelled AMD or Acid Mine Drainage too. So, to better understand AMD and ARD, let’s begin by defining some terms like pH -The standard measure of acidity. The pH scale actually measures hydrogen ion concentration in water solutions. […]
Cerro Verde began operations in April 1977, originally formed and operated by Minero Peru, as a state-run mining company. The electrowinning tankhouse was designed to produce 33,000 metric tonnes per year (mtpy) of copper cathode operating with current density of 184 amps per square meter (A/m2) and 88 percent (%) electrical current efficiency. In 1994 […]
Para la determinacion de este parametro, se realizan pruebas variando el pH, adicionando cal, a continuacion se muestra la determinacion del pH el circuito de Zinc del mineral de La Negra. De la tabla anterior se establece un pH de 10.5 ya que es donde se obtiene el maximo grado y recuperacion de Zinc.
