New Mount Isa Mines copper concentrator Ball Mill improves the daily grind. Improved flotation performance can be attributed to the recent commissioning of a new Ball Mill at Glencore's Mount Isa Mines Copper Concentrator. A third Ball Mill complete with a 3,500 horse power motor sits gallantly between the SAG Milling and Flotation sections at the
MILL CONTROL: BALL MILL CONTROL EXAMPLE Process Description The copper concentrator in Pinto Valley, Arizona processes a 0.4% grade copper ore from a nearby open pit mine. The unit operations consisting of crushing, grinding, and flotation process about 65,000 tons of ore per day in six overflow ball mills.
view of the history and evolution of the grinding circuit to date. The copper concentrator was originally commissioned in May 1973. Since then, it has been treating chalcopyrite ore from the upper ore bodies of the mine (1 100 and 1900 series), as well as the deep copper ore body (3000 series), at a
Kalyadi copper concentrator is designed to process 250 tonnes per day. The ROM ore is crushed in two stages. The ore is fed directly from the mine shaft bin through an apron feeder and a conveyor belt to the primary (jaw) crusher which operates in closed circuit with a
Modelling and simulation of the grinding circuit in madneuli copper concentrator 233 Work indices of the samples were determined by using standard Bond Work index test. The results are given in Table 1. Table 1. Bond work indices of the different ore types in Madneuli deposit. Plant feed Oxidised ore Sulphide ore Complex ore
The Cities Service Company’s Pinto Valley mine and concentrator lie about 6 miles west of the town of Miami, Arizona at an elevation of approximately 4,000 feet above sea level. The concentrator started its first ball mill in July 74 and all six were available by November. Every effort was made to reduce capital costs, consequently, each unit process was studied critically to eliminate
7/16/2004· Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copper-in-concentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite, sphalerite or galena. Chalcocite concentrates typically grade between 37% and 40% copper
Halving the secondary grinding energy meant only one of the two secondary ball mills would be needed. The predicted saving in operating cost of one less ball mill was more than two million dollars per annum. This paper summarises various plant trials that were conducted in the Copper Concentrator to decommission one of the two secondary ball mills.
The grinding mills convert the ore into approximately 230,000 tons annually of copper concentrate and 1,800 tons of molybdenum concentrate. The Client also awarded Fluor the follow-on work for the conceptual engineering and detail design for the extension to the 45,000 tpd copper concentrator building to house a new ball mill.
This paper presents results following the application of a sub-optimal control scheme, both through simulation and in situ, from the operation of Section C of the CODELCO-Andina copper concentrator plant. The algorithm permits the determination of the necessary control action at each instant of time in order to maximize a defined plant performance

Changes in metal prices and mine output over recent years have required the Copper Concentrator of Mount Isa Mines to operate at annual tonnage rates varying from 4.0 million to 6.5 million tonnes. Several circuit combinations were operated during this period utilising up to two semi-autogenous grinding (SAG) mills and up to two ball mills
Balls for use in mineral processing ball milling operations are designed for maximum abrasion resistance using high carbon content and high hardness levels. PRODUCT SPECIFICATIONS. SIZE Molycop manufactures forged grinding balls for use in ball milling and regrind applications in nominal sizes from 1.0” to 4.0” in diameter.
Training Scenarios. 1. SAG Mill overload due to an increase on the ore coarseness, 2. Low Stock-Pile level and its effects on the plant, 3. Constrained operation, with low water network pressure, 4. Secondary grinding. Constrained operation with sudden pump malfunction events and low water availability, 5.
The copper concentrator was rebuilt in 1973, with rod and ball milling and three-stage flotation, to supply the roaster and conventional blister copper smelter on site. In 1981, Mount Isa commenced anode casting as well. In 1988-1989, two 6.4MW AG/SAG grinding mills replaced the rod and ball mills at a cost of A$35m.
