Laboratory test for a water control system has been carried out using a simulator, a newly designed thermal gradient-type reactor.

In the calculation a slag making stage was simulated by many calculation steps in series, each of the steps being assumed in an equilibrium state. Results of the calculation were compared with experimental values measured in pilot and commercial converters.1. Calculated and measured matte grade changes were in good agreement with each other during the slag making stage. In particular, both of the changes showed that in the beginning of the stage there was a period of time for which the matte grade did not increase appreciably in spite of blowing. According to the present calculation, this was attributed to an increase of oxygen disolved in the matte.2. Calculated oxygen pressures at the beginning and the end of the stage agreed relatively well with those measured for the matte before blowing and for the converter slag after the stage, respectively. However oxygen pressures measured through the converter mouth during the stage were rather higher than those predicted by the calculation. Some of the measurements gave higher oxygen pressures than those measured even at the end of the stage.3. To explain the above mentioned phenomena by equilibrium calculation, a two-zone converter model has been developed. In the model the matte holding zone in a converter consists of two zones, i. e. a magnetite formation zone and a magnetite reduction zone, which are assumed in a different equilibrium state. By setting a proper ratio of the two zones, differences in oxygen pressure between the white metal and the converter slag at the end of the slag making stage were explained to some extent.","PeriodicalId":22754,"journal":{"name":"The Mining and Materials Processing Institute of Japan","volume":"69 1","pages":"281-287"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81745899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As a result of the leaching test, almost of all valuable metals in the cobalt crust were leached in the solution.By addition of the calcium carbonate in the leaching solution, iron was removed completely as iron hydroxide. In this time, the other valuable metals were not effected by the calcium carbonate.In the experiment of extraction, 10% LIX-84I kerosene solution was used. The extraction percentage from the leached solution with the 10% LIX 84-I kerosene solution were more than 99% for nickel, cobalt at pH: nearly 7.0 and copper at pH: nearly 2.0.In the stage of extraction, the separation of nickel and cobalt was difficult, because of the same extraction behavior. Therefore, the studies were occurred on separation by stripping. In the stripping from the organic phase containing nickel, cobalt and copper, copper was stripped with the hydrochloric acid solution at pH: nearly O. Nickel was stripped at pH: 1. After this operation, cobalt may be got by hydrogen sulfide.","PeriodicalId":22754,"journal":{"name":"The Mining and Materials Processing Institute of Japan","volume":"13 1","pages":"193-197"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82008467","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Two types of samples with different particle size fractions (J-A;-16/+100 mesh and J-B;-100 mesh) were prepared for the experiment. The main components of the clay sample were identified to be sericite, α-quartz, and hydrated iron oxides as main contaminants of iron and iron aluminum silicate hydroxide [K (Fe, Al) 2 (Si, Al) 4O10 (OH) 2] as a second phase of Fe-contamination. With a reaction temperature 100°C, aL/S ratio 5: 1, a spin rate of 500 rpm, a reaction time of 120 min., the optimum leaching percentage was obtained at 0.38 mol/l oxalic acid concentration for J-A and at 0.19 mol/l for J-B. Leaching percentages for J-A and J-B were then 83%and 96%, respectively. The substantial removal of iron reached to 86.2% and 89.6% as Fe2O3, respectively. Instead of high leaching efficiency of iron from the J-B, it is limited to wash out the leached iron species because of a little adsorption of iron species on the surface of clay. The whiteness of the leached clay with oxalic acid decreased with the higher content of iron in the product. The small amount of magnetic materials remained after oxalic acid leaching, could be removed by weakly magnetic separator and identified a mixture of ferrous oxalate by XRD pattern.","PeriodicalId":22754,"journal":{"name":"The Mining and Materials Processing Institute of Japan","volume":"14 1","pages":"847-851"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"78277668","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
