The low grade (0.07wt% Cu in average) Sonajil porphyry Cu deposit(PCD) is hosted within Eocene to Plio-Quaternary plutonic and volcanic rocks of the Urmieh – Dokhtar Volcanic Belt, NW Iran. The main Eocene dioritic body, which containsthe Cu mineralization, that is intruded into Early Eocene volcaniclastic rocks. Three main alteration stages:(i) comprising potassic (with major proportion of copper mineralization);(ii) later phyllic;(iii) and subsequent argillic alteration were studied in term of mass changes and element mobility. The graphical isocon methodwas used to illustratequantitative mass changes in the Sonajil PCD. Theresults of the analysisshow that Al2O3, TiO2, and MnO were relatively immobile during the hydrothermal evolution of the Sonajil PCD withthe average mass change factors of 1.04, 1.02, and 0.99 calculated for potassic, phyllic, and argillicalterationtypes, respectively.Therefore, it is possible that the hydrothermal evolution of the Sonajil PCDhas beenassociated mainly with minimal volume changes. In the potassic zone, K, Na, and Ba were enriched whereas Fe, Ca, and Mgwere depleted.This is consistent with the break-down of plagioclase and biotiteas well as alkali exchange reactions leading to the formation of microcline. Moreover, significant amount of Cu and S were added in the potassic alteration zone manifested bythe distribution of chalcopyrite and bornite. Withinthe phyllic alteration zone, SiO2 and some other trace elements were enriched whereas Na,…
Oxygen transfer, the process by which oxygen is transferred from a gaseous to the liquid phase, is vital in a variety of biological and hydrometallurgical processes, in particular wastewater treatment. The aim for this experiment is to evaluate how this oxygen mass transfer varies under a range of different operational conditions (E.g. Stirrer speed and oxygen flow rate), and formulate the optimal parameters for modelling a sewerage plant.

The article being reviewed in this assignment,“ Lessons Learned about Technology Transfer ” provides different lesson learned about effective technology transfer by researching and analyzing the technology transfer process in New Mexico during the past several years. In this article, the author expressed that New Mexico is a good candidate to investigate their technology transfer process because of two reasons. Firstly…

An analysis of the vertical tube type with fifty 1’’ diameter 16 swg tubes evaporator was carried out with the aim of determining the overall heat transfer coefficient of the system and to perform a heat balance over the evaporator. The experiment was carried out by measuring the mass flow rate of the inlet water and the condensate, temperature of the inlet water, condensate before it passes the steam trap and the surface area of the evaporator. The collected data…
will use the Ideal gas law and stoichiometry to calculate the Molar mass. Based on numeric and qualitative data we might make an assumption as to the identity of the liquid.
A special round bottomed flask
Pipette to transfer unknown liquid
accurate digital scale
A hot water bath setup.
Ice bath setup
We obtain the mass of the empty flask, aluminum foil (both pieces) and rubber band.…
we will discuss the concept of the mole while giving much prescribed instructions
on how to make each solution. One of the solutions you will be making, Iron (III) Chloride, will
take several days to make a solution of rusty water with sufficient mass of rust (Fe2O3) to make
the Iron (III) Chloride solution. Don’t worry you won’t need to watch it for several days, but
plan to start this lab early enough to complete within the allotted time. In addition, start this
experiment first and let it…
Preparation of Calcium Carbonate
Purpose: To create chalk (calcium carbonate) and to find the percentage yield in order to see the amounts of anhydrous sodium carbonate and calcium chloride were used up. Also to see if there’s any alterations like mass differentials.
1. To introduce the concept of “limiting factor” in a chemical reaction
2. To practice
a. Writing a balanced equation
b. Determining the number of moles of each reactant and product

Altered Nuclear Transfer, Blastomere Extraction, and a Somatic cell nuclear transfer.
Altered nuclear transfer (ANT) makes it possible for stem cells to be removed from an embryo without destroying the embryo itself in the process. Altered nuclear transfer could offer a way out of the current ethical dilemmas surrounding embryonic stem cell research. Normally, embryonic stem cells have been obtained by growing a human embryo into a cluster of cells that contain an inner cell mass. It is the inner…
