CV Persada Tambang Intitama TK 4.218 Paku is a partner company of PT Timah Tbk, which conducts primary tin mining using the open pit method. Primary tin ore processing includes comminution, sizing, and concentration activities. Grinding using a Ball Mill is an advanced process that aims to reduce the grain size of the material in order to obtain finer grain sizes (fine material) and prepare the right grain size for the concentration process of 80 s.d - 200 mesh. In this study, the variables used are feed rate, number of Ball Mill revolutions (RPM), and water rate. The experiment was used 27 times by setting variables in combination to get effective scouring results. The material at the study site is divided into high grade and low grade materials with primary tin mineralization types in the form of stanniferous veins and gossan formed due to the oxidation process of polymetallic veins. Variable feed rate, number of Ball Mill revolutions (RPM), and water rate are very influential on the results of grinding. The higher the feed rate, the number of turns, and the rate of water the higher the Ball Mill scour, but if the variable is too high it causes overload capacity so that the output volume decreases. The effectiveness of the grinding results obtained in sample 24 with the highest production value reaching 93.9%. The effective value is obtained from setting the feed rate variable 5 to 6 Ton Per Hour (TPH), 80 rotation RPM, and water rate of 10.800 liters/hour (l/h). The result of the maximum feed rate that can be done is 9.86 TPH with LPT is 236.64 ton/day. Thus, the average LPT target of the company's 230-240 tons/day Ball Mill can be achieved

Geoelectric measurements have been carried out using multichannel ResistivityMeter (Geores) tools with Wenner, Wenner-Schlumberger, and Dipole-dipole Configuration approaches on the influence of materials arranged in a laboratory-scale measuring tub design with dimensions of 194x184x80 cm. The measured method is the variation in resistivity value against each trajectory of the material. The method used is the variation of resistivity values for each path of the material that has been arranged in a laboratory scale measuring design. Geoelectric measurements were carried out on 7 lines (5 line in the West-East direction and 2 line in the North-South direction). The spacing between the electrodes of each line is 10 cm with 16 electrodes in one line so that each line has a length of 160 cm or 1.6 m which corresponds to the length and width dimensions of a laboratory scale measuring design. The electrode arrangement parameters are constant with respect to changes in the configuration selected from the geores parameters during geoelectric measurements. The measurement results showed that the identified depth reached 31.2 cm. The low resistivity value category has an interval of 374-4,397 ohm.meters at a depth of 0-12.5 cm, which is the influence of building sand material containing water and soil, while the depth interval is 12.5 - 31.2 cm ohm.meters (material category that is influenced by 2 iron rods, tin tailings sand, granite, gravel) with resistivity values ranging from 12,378–67,498 ohm.meters. From experiments on the influence of the resistivity values of the three Wenner, Wenner-Schlumberger, and Dipole-dipole configurations, it was obtained that the smallest absolute error resistivity value in the Wenner configuration was 5.01% against the overall average absolute error resistivity value of 10.16%.
