The cost of Ball Mill power usage is given as US 0.17 for kilowatt hour per ton of ore milled whiles the company 1 and 2 steel ball brands cost US1237 and US1338 per ton of steel balls respectively Technical Report, 2016. Critically, it will be suicidal to select any alternative of reagent without
Ore metals Cu, Zn and Pb are present in significant concentrations 500, 300 and 200 ppm respectively and the low FeMn ratios are indicative of a relatively oxidising fluid.
Jarosite and schwertmannite are precipitating in Davis Mill Creek, where stream pH is typically 2.5 to 3. Jarositerich mud forms in puddles and side pools along the edge of the creek. XRD of a bulk sample indicated minor gypsum, quartz, and mica. The jarositerich mud contains 33 wt. Fe, 3.2 wt. K, and 2500 ppm CuPbZn.
1. Introduction. The concentrations of trace metals in most natural waters are controlled by adsorption or coprecipitation processes. In theory, the former is the twodimensional accumulation of an ion at the interface between a preformed solid and the aqueous phase, whereas the latter is the simultaneous removal of a foreign ion during the formation of primary metal precipitates such as Fe

The Lower Carboniferous Khandiza VMS deposit is located in southeast Uzbekistan close to the border with Tajikistan. Currently awaiting development by Marakand Minerals Limited Marakand, the deposit comprises more than 14 Mt of resource grading 7.2 Zn, 3.5 Pb, 0.9 Cu, 130gt Ag and 0.4 gt Au.
terials were PbNO3 2, MnCl 2, CuNO3 2, FeNO3 2 and ZnCl 2. Means of Pb, Mn, Cu, Fe and Zn were calculated from triplicate. Soil analysis The soil samples were airdried at room temperature for 3 weeks, then ground into fine powder and sieved through a 2 mm nylon sieve. The concentrations of Pb, Fe, Mn, Cu and Zn in the soils were
The aim of the current study was to follow the develop ment of metal emissions from brake linings and tire tread rubber over the period 199519982005, and to put the emitted metal quantities in relation to other metal emission sources in an urban area. The focus was on Cd, Cu, Pb, Sb, and Zn, and for tires, chromium and nickel.
