Background:
This pre-processed concentrate is from a mixed of oxide and sulphide ore, from a mining processing company. The readings are % per tone of concentrate.
I used an NITON XLt XRF and got these readings.
Nb – 0.103, Zr – 0.012, Cu – 9.38, Pb – 7.28, Zn – 0.103,
Fe – 7.34, Mn – 0.070, Ti – 0.684, Ag – 0.063, Mo – 0.002,
Au – 0.020, Co – 0.062, Pt – 0.075
Other materials were below readable levels.
I experimented the following:
COPPER
1. I mixed the concentrate with sodium chloride 1:1 ratio then heated to 644 degree Fahrenheit or 340 degree Celsius, for 2 hours.
2. I then filter it through water, but I was only able to extract 50% of the copper.
Question #1: Is there a better way to extract the copper from the concentrate to get near 99% extraction?
3. I was going to direct electroplate the copper from the solution with 15% sulfuric acid, to get 99.99% pure copper.
Question #1: Would it be better to running it through an SX plant?
Question #2: Can I use reverse osmosis to clean the 15% sulfuric acid, back to clean the water and reuse the water again?
LEAD
1. After letting the concentrate dry. I was going to mix 10 – 12% coconut carbon with the dried concentrate then heat it up to 360 – 368 degree Celsius to extract 99.99% pure lead.
Question #1: How long do I heated for?
Question #2: Is that the proper mixture for the coconut carbon?
SILVER
1. After the lead process. I was going to mix Borax – sodium tetraborate - Na2B4O7, Silicon dioxide - SiO2, and Sodium fluoride – NaF and heat it up 1,000 degree Celsius to extract 99.99% pure silver
Question #1: What % mixture from each chemical is needed per tone of concentrate?
Question #1: How long do I heated for?
I would like to extract the Pt, Ti and Fe, but I do not know how.
From the reading of Mn, Co and Nb are they high enough in % per tone to try and extract it?
Is there a better way to separate then the way I am doing it?
Thank you so much ahead of time.
Sincerely yours,
