Thanks so much again Modest. You have been so helpful. I will check out these site. Happy New 2008. Thanks Dale

Hi Modest The ore is mill to approx. 0.5mm. I am using 99% sodium chloride it thought it would be more safe then HCI. No it did not heat under pressure and did not add oxygen. I do not have that type of equipment. If I did that would it only extract the copper? How about the other material? I don't know how to upload a image. Thanks again. Dale

Hi Modest Thanks so much for the reply. The link was very helpful. Thank you again. Dale

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 Au, 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, Dale
