This is rest of traditional mineworker of diamond which still flipping up to look for hope. This mining activity is including region Sebamban VI Kecamatan Kuranji Kabupaten Tanah Bumbu and there [are] around year of 1995. and this is mineworker pickings which still staying to get secuil hope. Most this mineworker comes from region Kalimantan south like martapura, new town, go abroad, pagatan or people local x'self. There is thing funny from this traditional mineworker, said them usually the mineworkers coming from far it is said has known location which will be mined from paranormal (" bright people") to get result larger ones.
It is they which still draping lives by mining of diamond traditionally. Only with machine capital dongfeng assembled x'self with pump to suck and a few creative modifications to accommodate material which in the form of wood and board and carpet applied to precipitated material and equipments applied tray to which wooden rengas they are to searching portion for and on behalf of family.
Simply this traditional mining activity can be described as following :
1. Water pump machine placed periphery basin to suck water coming from pool to be used sprays material taken and or material which has entered in precipitation board.
2. Water inhaled from the pool is flown [by] towards link pump having some tubing's applied to spray material which will be sipped and or material which has stepped into precipitation board.
3. Pump machine sucks applied to inhale material in the form of sand and gravel from within dig pool. By assisted water from link pump, the material in dig pool sipped by after sipping towards precipitation board of through (via paralon pipe).
4. The mineworkers usually cleans former of dig pool from the king sized wood or root or stones in pool. Commissioned in dig pool usually there are 3 people where 1 people holds machine gas string dongfeng to control rising or alights from every attraction of material, usually is adapted for condition of material. 1 people again undertook holds water tubing spray pool material and 1 people again undertakes cleans material from wood, king sized root or stones in dig pool. Whereas 1 people undertakes in precipitation board to spray material so that clean and 1 people again undertakes takes care of the pump machine or assists cleans material in precipitation board.
5. mixed Sand material and gravel of the water is admission in to precipitation board and cleaned continually with water sprayer. Before precipitation board admission of the material through carpet unfolded by concurrent with modification design of accurate board under exhaust tubing which in the form of paralon pipe. So if there is smooth fairish diamond, beforehand patch in carpet patching in precipitation board.
6. After material in the form of sand and gravel in precipitation board of cleanness (there is no mud), the material is input by sack for mobilization to tray pool. So from here activity of tray done to dissociate between materials which in the form of sand and gravel to get diamond.
7. Diamond got mostly fairish smooth like sand sugar, once in a while if chance again lucky they can get measure larger ones usually size pentol match or about 3 fiat ( term people local calls). The result usually is sold to collector which there are in village to be sold to martapura banjarmasin. sometime mineworker sells x'self to martapura if result gotten is fair to middling bigness to get higher level price.
In flow diagram can be described as following :
Pump Sucks Basin ---> Link Water Pump (to Pond Excavation & Precipitation Board) ---> Pump Sucks Dig Pool ---> Precipitation Board (in the form of material ready for washed raw-gold) ---> Tray Pool
