3 Terms and definitions
3.1 Metal ore
Usually, it is mined from metal deposits. Metal ores are generally composed of useful metal minerals (that is, ore minerals) and associated gangue.
3.2 specimen
The "specimen" mentioned in this regulation refers to metal ore specimens.
3.3 Collection Specimen
Specimens with scientific research, scientific popularization, ornamental significance, important economic value or commemorative significance, which are incorporated into the collection series.
3.4 Exchangeable specimen
Specimens that cannot enter the collection series due to their own defects or too many similar specimens in our unit.
3.5 unvalued specimen
The collective name of specimens withdrawn from the collection series refers to the specimens whose quantity exceeds the basic quantity of similar collections and loses the collection significance with the addition of new and better collections. This kind of collection can exit the collection series and be included in the exchange series after proper procedures and removal of the collection mark.
3.6 The Basic Quantity of Specimen
The minimum quantity of each collection is determined according to the principles of scientific significance, display value and appreciation.
4 Prepare
4.1 Numbering tool
-Enamel: apply it to the specimen or the container where the specimen is stored, so as to write the number.
-marker: used to write the collection number.
—— Brush: used for painting enamel on specimens.
—— Tray: used for temporary placement of specimens for easy transportation.
—— workbench: used for temporarily placing specimens.
4.2 storage device
-frosted glass bottle: used to store small or loose specimens.
—— Silk paper and sponge: used as the backing for placing specimens to avoid crystal damage.
-lead box: used to store radioactive specimens.
-paper box: used for storing general specimens.
-sealed bag: used to store samples that are easy to deliquesce.
-colored sealed bag: used to store specimens that are afraid of light.
-vacuum bag: used to store easily oxidized specimens.
4.3 sealing materials of relevant materials
file bag: used to seal the original materials related to the specimen.
4.4 means of transport
trolleys, humanoid ladders and small forklifts: used for transporting specimens in the warehouse when they are put into storage and moved.
4.5 other auxiliary tools
geological hammer, pliers, vacuum cleaner, small water spray gun, screwdriver, paper cutter, scissors, balance, scale, gloves and masks.
5 warehouse requirements
-proper ventilation equipment is available, and the warehouse should be kept at constant temperature and humidity (temperature 2℃, humidity 4%) if possible.
—— There is normal lighting equipment.
—— There are main passages and secondary passages, and the width should be suitable for passing through trolleys and small forklifts.
—— There are security equipment and fire-fighting facilities arranged according to specifications.
-inflammable, explosive, corrosive and other dangerous goods are strictly prohibited.
—— For super-grade and important economic value collections, special warehouses or counters should be set up for key storage.
6 Preservation and management
6.1 Preservation steps
1) Take the specimens out of the box or bag (bag) and put them in the tray on the workbench according to the original number or order.
2) Check the original label content with the actual specimen.
3) according to the classification scheme of the collection, classify the batch of specimens and put them on the workbench.
4) Check whether the specimen needs sorting, cleaning, repair and reinforcement. If necessary, it shall be treated according to Technical Specification for Arrangement of Specimen Resources of Metal Ore.
5) compare each kind of specimen with the original similar specimens in the warehouse and classify them into corresponding grades respectively. If it can't reach the collection level, the specimen will be directly listed in the exchange product and logged into the exchange product catalogue; If the number of collections at this level exceeds the basic collection, it will be eliminated at the bottom, and the redundant specimens will be downgraded or directly reduced to exchange items to exit the collection series and log in to the advance and retreat catalogue. This is the "dynamic management and last elimination" of the collection.
6) For the specimens that need to be collected, evenly coat .5 ~ 1cm× 1.5cm ~ 2.5cm enamel on the appropriate positions of the specimens (which is convenient for writing the collection number and does not affect the display effect), and leave them to dry. If the specimen is too small, radioactive, placer or powder, paint can be painted on the outside of the apparatus to store the specimen, such as the outside of the frosted glass bottle and the outside of the lead box.
7) according to the actual situation of the unit, the specimens are numbered according to the coding sequence of the specimens in stock, and then the numbered books are written neatly on the dried paint surface with a marker pen.
8) Carefully and neatly fill in the indoor label of the specimen and the record card of the collection information (see Appendix A and Appendix B).
9) Take photos of the collections one by one according to the requirements of the specifications.
1) write relevant information into the collection ledger and collection general ledger, or enter it into the collection database.
11) according to the type and size of the specimen, select the appropriate preservation apparatus. If the specimen is placed in the paper box, the original label (if any) should be placed first, and then the indoor label should be placed before the specimen is placed.
12) Specimens that are too big to enter the drawer of dense combined cabinets should be placed on a stable ground or specimen rack alone. Clip the original label and indoor label on the label board and put them in front of the specimen.
13) according to the book records, database records and the actual situation of the warehouse, allocate appropriate storage locations (warehouses, shelves, columns, cabinets, drawers, grids, etc.) for each collection and original materials, and enter the location information into the accounts or collection database.
14) Finally, put the installed specimens into the corresponding inventory position according to the collection classification, and put the original materials into the corresponding inventory position.
15) put the specimens that have withdrawn from the collection series in the area of returned articles.
16) Put the used tools, equipment and utensils in order and put them back.
17) Close the doors of cabinets and warehouses.
6.2 outbound
The collection must go through the normal procedures in accordance with the relevant regulations.
6.3 Daily management
1) The keeper of the collection should regularly check the warehouse environment to ensure the safety of the warehouse.
2) The keeper of the collection should regularly check the collections under his management, especially those that are easily deliquesced, oxidized and weathered, and replace the damaged packages and labels in time.
