Tailings in this study are the result of Jigs washing in the mining process. This 'mining waste' interesting to study because there is no information that explains the relationship between mineral content and geochemistry so that it has not been widely used. The method used to determine the mineral and geochemical characteristics of tailings is X-ray spectroscopy using XRD and XRF. The mineral found in the tin mine tailings on northern Bangka Island (Pemali, Jebus, Tempilang, and Mapur) is quartz and kaolinite. The trace element shows main Rare Earth Elements (REE) Ce, La, Nd, Sm, Ta, and Y with various concentrations. Radioactive elements are found: Uranium and Yttrium. They are thought to originate from type I granite rocks with acid-to-moderate magma-forming compositions. The affinity of magma forming granite tailings studied was High K Calc Alkaline and Calc-Alkaline. This explains the presence of REE and the radioactive elements in tailings even though they are not present in carrier minerals such as monazite and xenotime.

Indonesia have natural resources in producing rare earth elements (REE). The abundance ofmineral resources in Bangka Island is related to the strategic geological position of BangkaIsland formed on the Southeast Asian Tin Belt (Cobbing, 2005). Geologically, the REEdeposits are associated with acid rocks (granitic) and phosphatic deposits. This studyfocuses on primary samples taken directly from ex tin mining area and ex kaolin mining inMerawang District, Bangka. The analysis of the sample uses X-Ray Fluorescence (XRF) tofind out the REE content are Ce, La, Nd, Sb, Sc, Sm, Te, Th, Y, and U. The analysis resultsshow that the spread of elemental content in the sample tends to have a relatively similarpresence. But in Sample 1 shows the Ce element is the dominant element that is equal to25.19 ppm, equivalent to 0.002% of its availability in sedimentary sand in the ex tin mining.while on the ex kaoline mining area the results of the analysis showed that there wasThorium (Th) content in Sample 3 of 70.05 ppm or 0.007% and was the highest contentcompared to other elements in all samples.

Bangka Belitung is one of the tin-producing areas in the world which is characterized by the large number of granite rocks in the area as the rock carrying cassiterite minerals. Granite rocks found on Bangka Island are rocks formed due to magma activity from acidic volcanic processes. The availability of acidic water is possible due to the presence of acid-carrying minerals from granite which causes acid rock drainage or acid rock water which generally occurs in mining areas, ex-mining and exploration in tin mines. Before making efforts to prevent environmental pollution, identification is needed regarding the potential acidity of the rock so that the pH and dissolved metal content that endangers survival can be prevented to a minimum.

PT Semen Padang (Persero) Tbk is one of the cement producing companies in Indonesia. The supply of limestone used as the main raw material in the manufacture of cement is obtained through the mining process in the IUP area of the company. Mining roads are one of the facilities that must be considered in limestone mining activities because it is a major support in the process of transporting limestones obtained from the working Front. Inadequate road conditions can lead to less productive means of transport in the transport process, which causes production inaccessibility. The mining roads in the 242 working Front are considered to be poor so that a technical study of the mine road is required in accordance with the AASHTO Manual Rular Highway Design standard so that the geometry of the mine road is not good enough so that improvements can be made, engineering studies include road width, cross slope, superelevation, road slope, as well as a study of the carrying capacity of the soil and the influence of the mine road on fuel consumption. Based on the results of the study, the geometry of the mine road is as followsthe haulage width of one lane is minimum 14 m, the width of the haul road is two lanes of 24 m, the width of the two lanes is 25 m minimum, the superelevation value is 1%, cross slope is 48 cm, the slope can be 16% of the vehicles are transported while the slope based on AASHTO is 10%, the slope of the road becomes the biggest factor that influences fuel consumption because it makes the conveyance exert great power. Mine path geometry that is not suitable causes a time of barrier of 86.85 seconds with a cycle time of 22.3 minutes using an average speed of 15 km / h resulting in a production of 1,343.04 tons / hour, while if made temporary road the transport means can reach ideal speed with time on average 29 km / h and 27 km / h, cycle time 17.75 minutes with a production of 1,687.4 tons / hour.

The process of washing primary tin ore at PT Menara Cipta Mulia in the final stage uses gravity concentration method to separate mineral cassiterite from its impurity minerals. The separation process uses a shaking table with 2 stages of washing to minimize the waste of valuable minerals (losses). In the initial stages of washing, the primary shaking table and finishing stages use secondary shaking table. Currently the use of shaking tables at PT MCM does not have default standards in operation and still uses trial and error. Reseach method by varying the slope variables of the table in the primary tool shaking table 4 variations, namely 0.95°, 1.27°, 1.59°, 1.91° and washing water velocity of 3 variations, namely 0.6 m/s, 0.9 m/s, 1.2 m/s while on secondary shaking table tools 3 variations are slope that is 0.64°, 0.95°, 1.27° and washing water velocity of 3 variations is 0.6 m/s, 0.9 m/s, 1.2 m/s with this variable variation, the sample is obtained for the grade test and recovery calculation. The optimal results on the primary shaking table were at 1.27 degrees with an average recovery of 56.43% and grade Sn of 51.28%. Optimal water velocity is 0.9 m/s with an average recovery of 50.97% and grade Sn of 52.19%. While the optimal results for the secondary shaking table are at a slope of 0.64 degrees with recovery averaging 40.88% and grade of 71.64% with an optimal water velocity is 0.9 m/s with an average recovery of 32.24% with concentrate grade Sn 72.18%. The greater the value of the slope angle and water velocity be used, the smaller the recovery of washing tin ore produced but the smaller the recovery value indicates the higher the concentration of the resulting concentrate.
