Effect of slurry level error in flotation area against concentrate in process department Pt. Amman Mineral Nusa Tenggara
Slurry is a concentrated porridge that is still mixed with soil, chemicals, gold, copper and other substances. The process of control by machines made to the level of slurry by using a computer which then affects the resulting concentrate results. So in this research can be seen the effect of error level slurry (x) to concentrate yield (y) in mining flotation area. By using slurry level control data at flotation area obtained from secondary data i.e. set point data, process variables and concentrate on December 1, 2017 until 27 January 2018. PT Amman Mineral Nusa Tenggara especially Process Department, EI & C Engineering support not yet have statistical analysis to see how the relationship between the value of control level slurry with concentrate value with simple regression analysis method hence therefore purpose of researcher is to know the influence of in control slurry level at flotation area to yield result of concentrate. In accordance with case studies included, the results of the analysis found that there is an influence between error with the concentrate results and get a model to explain the concentrate every single unit error.
